I'm Edgar's age... I was 25 in '67, or for most of it. I was out of school and working at the lab, which I mostly loved doing. I wasn't happy about the war. I think I smoked my first pot in '66, with some girl friends, nurses who had gotten some at the hospital. We put towels under the doors, heh.
Never did try acid, on purpose anyway. I did have some laced pot once, from Arnie who lived in the Cloud Room... have no idea what it was laced with... (that was '73), when I was just renting a small art studio in a building by the beach and still had an apartment in Westwood. I had just broken up with the 'love of my life' - literally, I had just come upstairs after he drove off - and met Arnie at the top of the stairs. Took the joint and weirded out all by myself in the nearly empty room.
Not long after that I moved to a larger space in the building. Didn't see much of Arnie, come to think of it, but made friends with a bunch of other folks there. My claim to fame is that one of the Kipper Kids borrowed one of my lipsticks before a show at the place downstairs.
This might inspire me to get my scanner in action.
AHA - that Kipper Kid link mentions The St. Charles Hotel, that was my building. Quite a place. It had been fixed up by a couple of guys, Tom Sewell and Roger Webster, from a flophouse to art rental spaces (sort of).
Once I actually quit my apartment and moved in there it was a step to, ah, some other steps, including renting an old Eagles' Lodge space. But when I first slept overnight in my loft at the St. Charles, I would hear glass breaking and F-yous loud in the alley beneath my window... yipes.
