There's no official (or even unofficial) connection made with Zodiac, but something screams "Zodiac" to me. Area is right. Age is right. 

I'd like to learn more about this due. 

If anybody is interested, please send me a private message. Or respond to this post if the PM option isn't available anymore.

Thanks.

I am going to try to create map on Google and post it here as well for visual reference.

Here is the list in no particular order:

Hunter’s Hill rest stop on I-80

Dan Foley Park

Sheveland Park (may have been known as Circle Park)

Richardson Park

Sandy Beach County Park

Crest Ranch Park

Baylands Vista Point

On the hill across from the drive-in movie theater on Rollingwood and Benicia

Behind the condos on Tennessee Street across from St. Catherine’s Catholic Church

Under the bridge on Highway 37 and Fairgrounds Road

On the hill by the Masonic Lodge on Masonic Drive

Gravity Hill on the western slope of Sonoma Mountain off Lake Herman Road

Quote Tom Voigt: "This is a recent find of mine that I am particularly proud of. Did you know there was an escape from Deer Lodge Prison in Montana just days prior to the Zodiac's Lake Berryessa attack of Sept. 27, 1969?"Bullshit. This was discovered years ago (2013 or before). More errors by you.

Quote Tom Voigt on November 24th 2021: "Grinnell is basing this on the notion that the Belli letter had never ever been reproduced in the media prior to the 1978 letter arriving. Which, of course, is nonsense". This coming from a man who complains Redditors can't spell names. The hypocrisy is staggering.

Quote Tom Voigt November 28th 2021: "The Belli letter (at least the top part) was definitely published prior to 1978. I'll keep an eye out for an example". I'm still waiting. 

I'm curious if productions of Man of La Mancha played in SF area in the Zodiac years. If so, where? In more general terms, was musical fan Zodiac aware of Man of La Mancha? Is this why Don Quixote was on his mind? 

It only caught my attention because of the name of this branch and what they did...

They were called "Ranch Hands" and their call sign was "Cowboy". They sprayed the chemical agents (agent orange) at the time.

That is the way it was for the men of Operation Ranch Hand, the Air Force’s long-running campaign to defoliate jungles and, in so doing, deprive the Communist forces of concealment cover and food supplies. Ranch Handers had the hot, smelly, and dangerous job of spraying chemical herbicides over large expanses with maximum enemy presence and minimum protection.

The basis for Ranch Hand was simple. Americans fighting in the field wanted the jungle growth stripped from camp perimeters, lines of communication, and the Ho Chi Minh Trail, to better prevent ambushes by exposing the endless flow of North Vietnamese infiltrators and assisting in their destruction. Under the call sign “Cowboy,” Ranch Hand aircraft met these demands day after day by plunging into heavy gunfire over enemy-held terrain. Their hard work saved the lives of many US and South Vietnamese troops.

Statistics give some measure of the effort exerted by the force. Between 1962 and 1971, Ranch Hand operators flew many thousands of sorties and sprayed more than 9,000 square miles of terrain. They delivered some 19 million gallons of herbicide, 11 million of which were Agent Orange, the controversial defoliant that has been the subject of numerous inquiries 

So the ranch thing has always been a personal connection for me to the symbols as I think they are barnds, but the cowboy part (Tim holt comic) and the Air Force (wingwalkers) being coincidence with it seems like something to look at if it hasn't already.

Possible connection to Zodiac having problems from breathing chemical agents while spraying in Vietnam?

Anywho....just found some coincidence with it all.

His encounter with Hartnell talking with him must have been a very interesting moment. Here he gets to actually tell someone stuff and so includes that he killed a prison guard and escaped a prison. He has a good old chat with Bryan. Most offenders would be telling their targets to shut up in case they start to sympathize with them.

So following on from that I do have to wonder if Stine wasn't also selected so this time he could have a real chat about who he was, what he had done and to vent it all out on a listener before murdering them. Taxi drivers as a selection for a conversation with a stranger makes sense in that hypothesis. This is not mutually exclusive with obtaining a shirt piece or boasting about it in letters.

If Zodiac had found a new way to communicate would that not explain why the need for letter writing decreases after 1970? If so how is he managing to carry out these chats with people and yet remain elusive?

Which leads me to the think the SRHM crimes could be that. Abducts, takes them somewhere, tells them who he is, what he has done, has a conversation about it all and then after a few days, kills them. No need for communications and letters and calls to law enforcement.

It wouldn't surprise me either if he managed to find some hooker and would say something like, "Hey you know what my kink is? I like to pretend I am the Zodiac. Here is my hood". Or even a girlfriend/wife willing to entertain that fantasy play which isn't.

I think it was Ted Bundy's girlfriend who would wake up in the middle of the night only to find Ted with a flashlight on under the covers looking at her naked body.

And before thinking there is no possible way a woman would put up with such things, all you have to do is read about the women who visit serial killers, get married, have conjugal visits and are enthralled by the stories they tell them about their crimes which aren't even make believe, but the real thing.

So did the Zodiac evolve his communication to in person one on one face to face? Is that how he let it all out?

Furthermore the absence of a letter describing his Lake Berryessa crimes may be because his chat with Hartnell was sufficient to satisfy some part of that urge at least for awhile.
