Trippy Days

Harvey, I also thought the subject was extraordinarily patient with the geezer.

There's an old cartoon by some bigfoot underground gay cartoonist (ixquick to the rescue) Howard Cruse yeah I think that's who. Short story about a group of young friends who drop for the first time. One guy is the "guide," a designated non-tripper. He tries to be "trippy" (look! Scotch tape!) but is just annoying, and his fate, as I recall, was not pleasant.

Ah. Some google image searching turned up Howard's page about it. (The actual comic is probably online somewhere.) (But, ahem, you could buy his book.)

The subject at his trippiest reminded me of Ram Dass's story of how LSD experiments on seminary students made a shambles of normal controlled experimental procedures. Control group, after a while, might say things like, "I feel something, sort-of." Meanwhile, the tripping group was saying things like, "I SEE GOD!" Heh.
