Owlsey "Bear" Stanley was at Monterey 1967 with The Dead, at Woodstock too and at Watkins Glen in 1973. He produced LSD by the tens of thousands of hits in the '60's & '70's. He died in car crash today in Australia in 2011. He had moved to Australia to escape scrutiny here in the US for past sins! https://www.rollingstone.com/music/music-news/owsley-stanley-the-king-of-lsd-82181/
