"LSD came in 1965. In retrospect, it seems now as though all of the elements that made it possible for acid to do what it did were assembled there in the Bay Area. Ken Kesey had recently brought his well-we-started-in-Oregon-sort-of band of hippies, beatniks, ne'er-do-wells, always-so-wells, insane people, sane people, a few freaks and some hangers-on to La Honda, just over a few miles from Palo Alto. Mother McCree's Uptown Jug Champions had started evolving into the Warlocks, who would soon become the Grateful Dead. There was an emerging political, intellectual, revolutionary, coffee-shop type of scene, primarily in Berkeley. So it was like, "Well, we got the wiring in and the lamps in, let's throw this switch and see if the thing lights up". It did. I had been smoking grass for two years, but acid was like that times ten, with a bunch of interesting weirdness thrown in. Acid was different, it was very special, and you probably didn't want to do it every day."
