Grateful Dead Shows Streaming to Parks

Grateful Dead Shows Streaming to Parks


INTRODUCTION

I was a digital audio taper of live music performances for about 10 years, 1995 to 2005. A songcatcher (read Mickey Hart’s book of that title). Instead of attending Jerry Garcia’s funeral I purchased my first DAT deck and started digitally copying live shows as well as recording live performances. Archive.org has eliminated the need for that taper trading community, it was fun while it lasted. I retired my large DAT deck at the soundboard in Winters California at the Palms Playhouse where it probably caught some more good recordings from 2006 to 2010, or maybe longer. Still have a portable Sony DAT deck.

This past February I was invited to present at the Grateful Dead Scholars Conference held in Albuquerque. Good to meet all the people continuing the culture, but I was a little out of my element surrounded by academics. My presentation was on the collective consciousness of the audience and musicians. Most deadheads will understand this concept quite quickly.  IF at all interested please don't hesitate to request a copy of my academic presentation.


SOLAR POWERED MUSIC PROJECT

I am writing this blog because of a project I have been working on for sometime. It waxes and wanes but at the heart is a continuous stream of Grateful Dead music for any location. Technology is enabling the low cost, high quality sound to be amplified and presented in a solar powered package. Here are some of the components:

1. Archive.org like file access to a full dead show, ideally lossless quality
2. Raspberry pi computer to serve files
3. Low cost relatively high quality Digital Audio Converter (DAC)
4. Relatively low cost good amplifier and speakers
5. Way for community to select a show
6. Solar powered.

I have been experimenting with many different audio scenarios and think I am on the verge of one that makes sense. It is a DAC HAT that has an amplifier on top of a Raspberry Pi (Zero, Pi2 or Pi3) running a Linux OS and music serving software that is accessed by a cell phone like Moode Audio. The gizmo isn't as important as the vision. My vision is for Golden Gate State Park, or any park, to have tree mounted speaker systems that can play a show. Alternatively, Bluetooth output could be multicast to anyone with headphones who then could listen into the show simultaneously with others in the area.

I wanted to host an example of an audio box that plays grateful dead concerts. They played some 2,500 shows, most of which are available online at archive.org. Many of these shows are new streaming high quality versions of the taped shows. In particular, a new form of show is emerging that has mixed audience sounds, soundboard recordings plus taper versions of the shows. These matrix recordings can be an amazing blend of the best aspects of the shows. The hardware/software solutions will lend themselves to any other band hosted at archive.org, etree.org, or an internet radio station. Anything streaming can be now amplified in high quality for low cost.

The current state of development for this concept is below. A 20 watt PV panel, charging a 7 amp hour sealed lead acid battery with a pulse width modulation charge controller. This solar and battery powers the Rpi and DAC HAT with the amplifier to power the sony speakers. The speakers are not weatherproof, so this can not be pole mounted yet. The concept is coming along nicely.



DEMONSTRATIONS

On May 8th 2017 I was able to set up the music at Red Rocks stage and play the 40 year old, remastered version of May 8th 1977. Red Rocks is open to the public as long as there are no performances.

I also set up the system near Folsom Field before a Dead and Company show 2017. The music seemed to be a draw for people to congregate around the 40 year old live performance, again May 8th 1977 Cornell Universty Barton Hall Grateful Dead show. Here is a fun publiclly available matrix recording on archive.org https://archive.org/details/gd1977-05-08.111493.mtx.seamons.sbeok.flac16 . The one I was playing is from Rhino, http://www.rhino.com/product/cornell-5877.

Stay tuned to this space as the audio solutions become packaged and tested for the playing of music in the parks.

Rpi with Supstronics x400 HAT



In this blog posting i am concentrating on combining the Raspberry Pi 2 or 3 with the Suptronics x400 which I picked up for less than $26 including shipping. This has gone up in price and took over a month to arrive. I picked this particular digital audio converter (DAC) because it connects directly to the RPi3 GIPO pins. An external DAC can increase the quality of music out of Raspberry Pi computers because they have better audio components than the low cost Pi components.  The x400 has three different outputs, RCA jacks that can be connected to an amplifier, headphone jack that uses an amplifier circuit and speaker connections for up to 20 watts of amplification per channel. I like that jumpers can be used to turn off sections of the x400 that aren't needed. I also like that it has onboard hardware volume control, even though I typically use the software volume control on the Moode Audio software. The jacks are not of high quality and are attached to the board in a flimsy fashion. This can be modified for anyone wanting a better connection.

Above Rpi2 with x400 HAT running Polk Audio speakers
Moode Audio sets up the x400 Hat quite nicely. Just select the x400 DAC from the list of I2S audio devices, reboot then apply the MPD again. I set the system settings off an ethernet connection including the wifi settings, then reboot and removed the ethernet cable. Then the Moode Audio interactive software should be available on your web browser at the local wifi address and will play the selected music through the x400. You can use the RCA audio output jacks, the headphone jack or connect speakers to the wire lugs. Again, the audio connections on the x400 are a little flimsy so be careful not to break anything off.  

One reason I chose to experiment with Moode Audio is because it has a customization section which includes filter options for the Burr Brown PCM5122 chipset. The x400 includes this PCM5122 chip so you can on the fly change between different digital interpolation filter settings. Some fun discussions on the internet on these different filters (see links below). My old ears can’t tell the diff, but yours might.

Originally I installed the x400 on a Rpi3, then looked at my inventory of Rpi boards and thought it would be better on the Rpi2 with a $3.50 usb wifi dongle. Used an old laptop power cord who’s socket fit the x400 power input. For under $70 US (plus microsd and power supply) we have a system that is portable, low energy consumption, plays and amplifies music quite nicely with an interface off any web browser.  

Update to Rpi3 and Rpi2 discussion now includes using the $5 Rpi Zero. Soldered GPIO pins to the Zero and screwed it to the Suptronics x400 and after two attempts at soldering it worked!

Three variations of Rpi's and DAC HAT.
These systems have been working very nicely with the latest version of Moode Audio software, amplifying the sound to various speaker configurations.

There are some new HATs from Suptronics which promise to provide affordable sound from Rpi integration. New boards and kits can be found at this web address: http://www.suptronics.com/ My own work is focusing on the x5000 series for solar powered music solutions. Stay tuned to this and other blog entries listed below for any updates. 15 second video of solar powered Suptronics HAT system: https://goo.gl/photos/w775JvDVJfxWM1YSA

Introduction to Music with Rpi’s

Introduction to Music with Rpi’s

Going to try and explain my experiences in setting up a music solution utilizing Raspberry Pi technology. The solutions may be applicable to older generation of Rpi’s, but I am working with Rpi2, Rpi3 and Rpi_zero.

As I have written previously, the Raspberry Pi lends itself to playing music (see posting about the uniqueness of the Raspberry Pi 2). The Rpi2 and Rpi3 systems have many options for outputting music including a headphone jack, HDMI port for high quality SPDIF 5.1 surround sound, and many USB options for both audio input and output. Various manufacturers also offer audio boards that connect to the Rpi GPIO pins; these boards are called HATs. Additionally, the Rpi3 has onboard bluetooth signal which can output audio to the many bluetooth audio devices available. I have been tasking myself to produce an audio system that is low cost, possibly solar powered, and ideally streaming music from the collection of live music hosted at archive.org. I think both the hardware, software and wireless technologies have recently come together to enable this vision.

HARDWARE
Raspberry Pi system on a chip combine functionality with low cost. There are many new versions of SOC solutions. I am sticking with the Raspberry Pi Foundation's because of their proven costs, as low as $5, fits the goals of my audio project. $5 is the cost of their hard to acquire Raspberry Pi Zero. I experiment on the Raspberry Pi 3, a $35 solution that has wifi and bluetooth wireless capabilities built into the board.

My goals for this project are to get the highest quality audio at the lowest cost. These are subjective terms. With the price point of Rpi gear so low, the audio solution should also be low, to a certain extent. Also, most of any challenges I've experience with Rpi gear is because I've either used inexpensive power supply or an inexpensive microsd card. It pays to not skimp on these important factors.

What I have noticed is a leapfrog in the ability to obtain and play music from all around the world using low cost devices. And the sound can be of quite high quality.

ENERGY
Because my goal is to make a stand alone solar powered music player I need the energy consumption to be low. Testing the RPi3 found that it uses between 3 and 4 watts, but often much less. Typically a Rpi with a USB audio solution will use about this much energy. With an amplifier connected the system will use a little more than the rated output of the amplifier if you are playing at the highest volume.  An important system factor is how many power supplies will be needed? Testing showed a complete energy useage of 4 watts for a Rpi and an amplifier. So a 5 watt solar panel could theoretically power the music system for as many hours of the day the sun is shining. A small battery charged by the solar panel would help during cloudy weather.

An important factor is what kind of power sources you have. If you are wanting to use only a standard Rpi USB 5v (and always have at least 2 amps), then you probably want to go with the USB audio card route. But if you need an amplifier and have a higher voltage supply, or 12 V battery from a car, then you may want something like a Suptronics x400 solution. Many of these solutions will work very well for a car application, headphone only, or amplified stereo.

A pi Zero running v3.0 MoOde used 5.16V and 0.19 amps which is 0.98 watts running a USB audio card and a wifi dongle through a USB hub. While starting up this used more power for a very short period of time. 1 watt powered the pi Zero headphones, slightly higher when performing wifi interactive communications. The Rpi3 used 0.26 amps or 1.35 watts for the same functionality. 

SOFTWARE
While evaluating the hardware, I was also evaluating software. Usability is important, so software and the user interface became another thing to evaluate. I like using my android phone as an input device for music selection, and in my opinion it is a plus if others can use their own devices to interface with playing music.

One of the interesting aspects of the Raspberry Pi computers is that they can use a variety of operating systems. At the time of this writing the operating system I prefer is called Pixel, Raspbian Jessie 16.04. For a stand alone project like this music project a customized music software/OS can be used like Volimo or in my case, Moode Audio.

For me, I’ve found Moode Audio to be an easy software package to use which meets my current evaluation needs. Using an android program called Fing I am able to see the Moode Audio wifi connection address on our local wifi network and then go to a browser to put in that numeric address. The Moode Audio user interface starts on your browser then you can change settings, pick music, create a playlist and more. People with laptops, tablets, iphones and androids are all able to access the music server, control volume, choose an internet streaming site, or pick from my many FLAC files.

Had one small challenge when our wifi setting mysteriously disappeared on Moode Audio. Had to reconnect to the ethernet, put in the wifi name and password again and everything was working once again. One thing that that Moode Audio doesn't stream music from archive.org directly, but does using Airplay.

There are some software developers who work on donations and Moode Audio is one of them. When I find software and obtain value from it I try to send some Paypal bucks off in support as I have with Moode.

The evaluation has been broken out into the following audio sections:

And a related post, Uniqueness of the Rpi.

Rpi Zero w/ Two Different Inexpensive USB Audio Cards

Rpi Zero with a Generic Low Cost USB audio Card & Zero with USB and a PCM2704 chip from Texas Instruments.

Lowest cost Rpi audio solution I have found is using the Zero with a inexpensive wifi card and a USB music card, total cost $10. I found audio popping with this scenario. But at a slight increase to $11.50 the sound quality is much nicer using a USB with the PCM2704 chip from Texas Instruments. Both options require additional $'s evaluation for microsd card and power supply. My friends at the Raspberry Pi Discussion Forum turned me onto the PCM2704 low cost USB card that in my opinion outputs nice acceptable sound quality (thanks clacktronics for the suggestion).
MoOde software over wifi from Rpi Zero powered USB hub w/PCM2704 audio.
USB is complicated here, but will be simplified. Zero has a camera too.
Inexpensive USB audio, PCM2704 on bottom; both work on Zero w/MoOde, hot swapping is OK
I will be reducing the USB wiring by soldering the wifi and USB audio with PCM2704 in place above the zero, then put into a small case with power input and audio output jacks showing. My initial attempt to reduce the USB Hub was a complete disaster, disassembling the case and trying to solder the USB Audio card to the USB Hub did not work for me, mostly due to my poor soldering capabilities.
The USB Hub which was destroyed by trying to attach the USB Audio directly.
My goal is to get a tiny package, something like a tic tac container. As you can see, the Rpi0, USB Audio and wifi can easily fit except the USB Hub isn't there.

ENERGY
A pi Zero running v3.0 MoOde used 5.16V and 0.19 amps which is 0.98 watts running a USB audio card and a wifi dongle through a USB hub. While starting up this used more power for a very short period of time. 1 watt powered the pi Zero headphones, slightly higher when performing wifi interactive communications. The Rpi3 used 0.26 amps or 1.35 watts for the same functionality. 
Solar powered w/Li-ion battery, Rpi0 with USB Audio, wifi and small speaker.




This tiny solution would enable an inexpensive car audio system controlled by a cell phone. Or just listen with headphones. 

CHROMECAST AUDIO
The comparison of these USB audio systems needs to be compared to a Google Chromecast Audio because the Chromecast has great functionality with lots of audio software. Other very low-cost solutions exist that don't have an amplifier including the items in the photo below (counterclockwise from the top: Rpi0, USB audio card, USB audio card with optical SPDIF, Chromecast Audio with analog and optical SPDIF).

The Chromecast Audio puck is $25 US and has the functionality of a wifi enabled Rpi with audio output, similar to the Rpi0 and USB SPDIF output card shown above. There may be audio quality differences. Through software, I am thinking that the USB audio can be configured to mimic the Chromecast Audio functionality. This may require some skilled software people. It is quite easy to connect many audio services to the Chromecast Audio puck.

Breadmaker



It is ridiculous how much gluten free bread costs at the markets. And the loaves are tiny. I've been contemplating how to bake my own for a few years now. A well respected bread maker by Zojirushi of Japan became available to me. Purchased at a reasonable price. It had been at the 2nd hand store for a few months. I went on a particular day that made the price low with multiple discounts. A quick check on the internet showed these sell new for $200 or more, so I took a chance.

The n15 by Zojirushi
It is a bit industrial, lots of metal and an exposed heating element inside the baking compartment. Some clunky sounds while the dough is being prepared. One interesting aspect is that it only uses 500 watts of power. That means I can run it off my solar inverter. I've always been an advocate of solar cooking.

After getting it home, the internet revealed a user manual and some recipes. I wanted to try it out with a standard flour recipe first to determine if is working properly. So miraculously got all the right ingredients from our kitchen, and a couple from the store. Buttermilk and yeast was purchased.  I think the yeast was the problem on my first batch of standard white bread. I purposely purchased the yeast packages with the latest expiration dates, but that didn't seem to matter. It was dead for my purpose. The loaf didn't rise, only half a loaf, very dense and slightly burnt around the sides.
First attempt at bread making ingredients.
Ingredients placed into bread maker baking pan, yeast on top.
I went to the store to get some new yeast, instant yeast, a pound of it for less than $5.  While at the store, the puppy had jumped up on the stove and ate some of the first bread baking experience. He hasn't done anything like that since he was new born, a year ago. Bad dog.
Ingredients for second batch, salt (1t), sugar (2T), yeast (2.25t), butter (2T), flour (3C) by weight and buttermilk (1.25C).
The second loaf did the rising that it was supposed to, but for some reason collapsed. My son had been playing his euphonium at the loudest volume I had ever heard. After the second rise of the bread I had peeked into the maker and saw a nice dome on the loaf which had risen to near the top of the baking pan.When all the baking was finished, the dome had collapsed. No worries.
Collapsed bread next to baking pan.
Looks OK, right?
Taste testers indicated that the bread is good!
Bread, some eatin...
My next try will again be a white loaf during a quite part of the day, probably with powdered milk.  I am working towards the gluten free version very soon.

By the way, third try on the white bread was excellent.

Quick video of bread-maker completing and first look at white bread. still trying to upload the video.

Bread didn't collapse, yeah!
Looking better, and tastes....great!

********* Gluten Free *********
Customer service at Zojirushi said gluten free cannot be done with the n15. The recipes and instructions for gluten free are challenging.  The preset programs aren't right, and all the ingredients listed in any recipe were double what my breadmaker could handle, so I halved as best as possible. And I used a pre-packaged gluten free mix which included at least three of the parts needed. 

Ingredients with associated packages
From Left to Right: baking pan, yeast (1.5t), apple vinegar (1.5t), honey (1.5T), salt (0.75t), flour mix (2C), 2 eggs beaten, milk (0.75C). Not shown, vegetable oil (1.5T).

The program I selected does kneading, two rises for 2 hours, then 44 to 52 minutes of baking.
A newer model breadmaker with a specific program for gluten free shows 17 minutes knead, 5 minutes rise1, 5 minutes rise2, 25 minutes rise3 and 60 minute bake. So I'm just trying my best on this first attempt with a wrong program. Plus I was using some proven live instant yeast, instead of active dry yeast recommended on the newer model. This yeast stuff is quite complicated.

The first attempt for gluten free wasn't a success.
First rise took much too long, as did the second one. Note finger pressed into dough shows it had started to bake.
With at least 30 minutes left on the baking program, I took the loaf out because it looked done from the top.
Bread is edible, but not at all right.
This particular bread maker isn't set up for gluten free, unless you wanted to be uber creative and manually mix the yeast in an hour after the other ingredients were mixed, wait 5 minutes, punch it down, wait 5 minutes, punch it down and then keep an eye on the baking time. Let me know if you want me to try this.

So the moral of the gluten free breadmaker story is, get a bread making machine that specifically has a gluten free program, something like this: knead, rise for 5 minutes, knock down, rise for 5 minutes, knock down then wait a few minutes and bake. 

************ Back to White Bread ************
I purchased some powdered Buttermilk blend, 12 oz for $4.52: 1 C Buttermilk = 4 T blend + 1 C water. That is about $0.95 per loaf. I also picked up some flour at the bulk bin for $0.74/LB; about $0.60 per loaf. For powdered bread, just add water this is a very good scenario.

Successful Irish soda bread, with gluten.
A Irish Soda bread baking was successful using the following ingredients: salt (1t), sugar (2T), yeast (2.t), butter (2T), raisins (0.3C), flour (3.3C) by weight, caraway seeds (2t), water (1.3C) and buttermilk powder (1T). There were three rise sessions in the breadmaker. Took 260 watt-hours of energy, 4 hours to complete the cycle and 0.5 hour to cool down. The taste was dominated by the caraway seeds. Not like I remember as a child, perhaps it was coated in powdered sugar back then. Below is a picture. I ate that slice in the hopes that I can tolerate gluten if fresh baked.

I can now make a multitude of bread recipes with gluten in the old breadmaker. Trick for my high altitude of 6,000 feet is to use less yeast. Feel free to leave comments, hope this helps someone with their baking.

$5 Music Box Server



After posting about the uniqueness of the Raspberry Pi 2 last year, I have purchased a 3 and a Zero.  This has all been tinkering, figuring out how low cost internet of things computers like the Raspberry Pi family can be put to good use.

This Blog post is about using the Zero 1.3 version to host a music library and shuffle songs to a stereo for listening. I am using a standard Raspbian Jessie operating system that was originally built on the Raspberry Pi 3, but works in the Zero with no issues. It is loaded on a 16 GB microSD card which boots the Zero. My only issue with the Zero is limited USB ports. If I had one more USB available, I could remote control the Zero music using WiFi.

I like Banshee music player because it has a graphic equalizer and has an Android phone app for remote control. I can't say that I understand all the Banshee functionality, but it seems to work for this particular application. Here is the music box server story.

Busy photo showing Raspberry Pi Zero (lower right) and other peripherals.
A few years ago I ripped all my music CD's to FLAC files, a lossless format that I thought would be good for future use. I now have many music folders, and 7,000 music files to choose from that were originally my CD music collection. I put them all onto a $35 hard drive for archiving, the Western Digital PiDrive with 314 gigs of storage, of which about 200 gigs is used by the FLAC file storage.  You can get any storage device you choose, not endorsing the WD hardware. I don't consider this hard drive cost associated with the music server because it is a backup archive. That hard drive is shown in the photo above. It has a bright white light. That is connected to the USB power cord, which then sends the power to the Raspberry Pi Zero. The hard drive USB data cable is connected to the USB data hub (red light in above photo) which also has a wireless keyboard, wireless trackball mouse and USB audio card. The red wire is the analog music which delivers the music to my stereo amplifier. Lots of wires.

The Raspberry Pi Zero has a HDMI mini to standard plug which the monitor is plugged into.

The monitor, wireless keyboard and mouse can be removed from the setup once the music is playing and in shuffle mode.  I have checked the power usage, it is 37 watts with the monitor, and 4 watts without. The hard drive, Zero and USB hub with peripherals use only 4 watts of power.

4 watts of power used for music box server without monitor.
The power is managed by a plug-strip with monitor, high amp output USB power and the USB hub power. Turning the plug-strip on boots up the Zero and goes into desktop mode. I click on the Banshee program and wait until it is fully loaded by watching processor utilization. Then select all artists and hit play. It shuffles the songs, and I get to listen to a random selection of my own music. I assume I could automate the process of running Banshee and automatically playing if necessary.
Raspberry Pi Zero ver 1.3 Running Music Box Server
As far as the music quality is concerned, it is OK. The very inexpensive USB music card has both audio output and microphone input. I assume I can get a DAC solution with much higher quality, I just haven't seen the right solution for my purposes yet. Waiting on some Kickstarter Pi DAC that can provide a SPDIF input (Please don't tell me about the Cirris Logic DAC, way too complicated).

This $5 Zero version 1.3 isn't easy to purchase. I had to wait on vendors mailing lists until they were back in stock. It seems amazing the functionality/price ratio for these systems on a chip (SOC) devices. There are peripheral costs. The Raspberry Pi Foundation keeps the costs low by not having additional functionality which each use case may not require.

Hope this is an interesting Blog. Feel free to comment. Thanks.

Garbage at Ski Area Slopes

In a few day's time I was able to visit four different ski areas and perform a standardized exploration of how much garbage could be found. Here is that experience.

First steps in this journey were taken at Mary Jane ski area in Winter Park Colorado on July 4th. I walked up the Panorama lift up to Parson's Bowl and then came back down a different route. Along this and all the journey's I used existing foot paths as much as possible. I left as little footprint as possible at all times. For this first trip, I was targeted at getting some of my own garbage that had been left, a telemark ski binding cable. I had lost it in 20" of snow powered on-top of 12" more powder. But found it exactly where I had remembered loosing the piece.


At the bottom of the ski slope I collected all the garbage and took a picture to document the amount of garbage. Below is the Mary Jane litter.


Then, I was taking a trip from Colorado to San Francisco and decided to stop at ski areas along the way. First stop was Park City Utah. I standardized the trip up the mountain, going 1,000 feet up, under a random ski lift, then came back down a different route.


Next stop was Heavenly Valley just south of Lake Tahoe in California. Same routine, 1,000 feet up, then a different route down.


Last stop on this journey I stopped at Alta just east of Salt Lake City. 

plus there was this extra garbage that I had collected, but didn't have space to carry up and down so left on the well traveled maintenance road.


Looking back on the photos it appears to me that Park City was the cleanest. But I had thought Alta was best. At least the wild flowers were the best I have ever seen. 




There are many more examples of garbage on the ski slopes in the form of abandoned infrastructure. Concrete foundations, piping, wires left exposed. 

When traveling back I was possibly going to hike up Steamboat Springs, but while traveling through I didn't have the energy. Some Forest Service people told me that those slopes have lots of garbage. What I would like is to have a Forest Service or Bureau of Land Management (BLM) relationship that first develop the standard audit process, then can grant access to ski areas to compare and contrast the land stewardship cultures. Hope this journey helps keep our ski areas as clean as possible. The irony that I had my own trash that needed to be picked up isn't lost on my experience. 

Of course, the air travel miles that skiers use is far greater an environmental impact than any of this litter.  




Whale Story

Wrote this a few days ago, July 9th, 2016. It was a four part message.

Part 1

Stayed over in Stinson Beach last night, then this morning moved to the public parking area and backed the car into a space right at the beach. Had some excellent Prius brew coffee and a crock pot stew of chipotle sauce with tuna on previously home toasted corn tortillas. Then I headed out walking north on the beach. Hadn't really explored that previously. Took some photos along the way, one of a ocean surge wall to protect the beach property next to a home with PV panels. Two different strategies for climate change. It was overcast but burning off, cool ocean breezes.

As I was contemplating the waves, each new wave sweeping out the old and bringing in a new event, new opportunities, new reality, I noticed a paddle boarder up ahead.  Not much happening that time of the morning. Earlier I had seen some boats close to shore, couldn't tell if they were tour boats or fishing boats. There was some bird commotions too. And then I saw a whale's back. The paddle boarder was right near it, and paddling in the direct the whale was heading. Then I saw a clearer sighting, took my phone out and started shooting photos. Some really good views of the whale(s) feeding very close to shore, possibly 100 to 200 yards off shore. The feeding died down, whales gone, and the paddle boarder was moving along in the same direction as I was and then came to shore in front of where she was staying. Her camera battery had died, but I sent her some photos I had taken to her e-mail account. One very excited paddle boarder.



Continued to walk as far as I could north, 2.5 miles, then turned around. I began wondering why I didn't  go into the ocean when I saw the whales? They were so close, I could have swam with them. People travel the world and pay enormous fees for such an opportunity. How would that work? Is it too cold? Would it be safe? How far out would the whale need to be for me to go swimming? Could I strip down to my underwear, they are black and look like swim trunks?

Let me know if you want to know the rest of the story.

******************

Whale Story, Part II

Where was I, oh yeah, walking back. Planning, thinking if I see another whale what would be the conditions that would get me into the water. If I was to take off my clothing I would need to weigh them down because it was getting a little windy. I picked up a rock and continued walking carrying the rock.

Well guess what?

Up ahead there were more people on the beach in one place. This was noticeable because the beach was quite empty.  They were looking out into the ocean. And again, the tell tale signs of birds. Then, again, spotting of a whale back's. It was feeding time again, but the whale(s) were a bit out, possibly too far out to safely go swimming closer. As I walked towards the people, a humpback came up out of the water filling it's mouth with fish. It smiled, it's head two yards out of the ocean surface. And it was closer, possibly a football field away. The people watched, and I did too. It seemed like things were dying down as I passed the people. They were dispersing. I sat down on the high side of the beach, took my shoes & socks off and removed my hat, sat down. Waited..waited, like coyote waits. Then it happened, a whale, closer, came out of the ocean heading my way. I made my move. 

Took off my long sleeve highway-orange shirt, dropped my pants, packed them into my hat along with the rock and went into the ocean. I swam out as far as I could still stand in the water. Waited. Yes, it was cold. Colder than I would have thought, but not the coldest ocean I've experienced. A whale, again looked like a humpback, was slowly going down the shore line feeding. It came about 100 yards away. Nice to see up closer. Of course I was sending it telepathic messages to come see me. It seemed like I was in water that was too shallow for a face to face meeting. The whale(s) came up a few times.

It calmed down again, and to keep from getting too cold I rode a wave to the shore and got out drying myself next to my tiny beach camp site.

Again, whale(s), so I went back into the ocean. Why not, I was still a little wet, and this time the whale looked even closer. So I ran in, yelling to a couple standing there "It's headed this way!"

I went a little further out, still able to stand, on my tippy toes and still breath air. I noticed the whale was breathing too, heading right towards me. I was 50 yards out, and it was another 50 yards. Birds were flying above, feeding on scraps a whale might have missed. It was now perpendicular to me and the beach, rising up out of the ocean, more than usual, crusty mouth of what looked to me like a humpback's head. We said hello, and it was on its way past. A few more feedings, then gone. I rode an excellent wave back to the shore, standing up after the ride in one foot of water. Walked back and dried off. As I left my beach site I remembers to look back and my hat was still in the sand. Further down the beach I couldn't find my sunglasses. So went back to my camp but they were not there. A pair of sunglasses I had found were now lost. Funny, I had just picked up some broken sunglasses off the ground at Heavenly Valley ski resort the day before. Waves of ownership. No worries, I have one more pair of sunglasses that I had found still in the car.

It feels like I have good whale karma. I remember seeing a whale every day while in Hawaii at each of the different islands. It just seems to happen. Like it did today. Maybe someday I will be able to ask a whale if we have met before?

But the story doesn't end there, something else just happened....

Whale Story Part 3

So the other thing that happened later on in that day was after I had taken a nap in the car.

But first I have to explain a little bit more why I got out of the water the last time. You remember, I had been swimming within 50 yards of the whale? Well, at the same time I saw a dorsal fin. Now, I am no Marine Biologist, but I thought to myself that is either another whale or possibly a shark. Well, seeing as there was  feeding going on, and again I am not a marine biologist, I thought it would be a good idea to get out of the water.

Now, back to the afternoon event after I had taken a nap in the car. I walk out to the ocean, and right there and then there is a whale with its nose sticking up out of the ocean having just grabbed a mouth full of fish. Ocean water running out of its mouth. More wales were feeding up and down the coast. I tried to get a selfy photo of myself and a whale. You have any idea how difficult that is? Getting a picture of a whale back or a whale coming up out of the ocean is tough enough. I don't know if I was successful, many photos but I can't see off my phone if there are any successful whale selfies. Will let you know...


The next morning I got up early and drove away from Stinson beach, but not before going out to the beach. Deserted except for a person sleeping on the life guard stand. No whales, no boats, no other people.

However, as I drove up, up and up out of the low lying town I noticed something else. Let me know if you are still interested in one more installment of this story.

Whale Story Part 4
As I was saying, I was driving up up and up out of the town of Stinson Beach after having spent a day with whales.

As I drove up, I notice boats heading towards the beach, and more boats, and in the distance even more. Then I noticed the tell tale signs of blow holes spewing water out into the air above the ocean surface. From the high vantage point I was able to see many different areas where whales were coming above the water. And then I saw it, for the first time, a tail. The ocean was so calm that morning not like the day before when it was choppy. I hadn't seen any tails. I didn't see any mouth above the ocean, but lots of black backs. At one point I counted five blow hole events at the same time. Hard to say how many of the majestic mammals where under the surface that day.

There seemed to be a mad rush for the boats of all different sizes to get to see the whales. I don't know how long the whales had been there, and don't know if they have left, but I did. And feel blessed to have been so close, so lucky to have seen this event. That is my whale story.

And then this happened a few day's later in the San Francisco Bay:
