My own acid-eating experience is limited in terms of total consumption, but widely varied as to company and circumstances ... and if I had a choice of repeating any one of the half dozen bouts I recall, I would choose one of those Hell's Angels parties in La Honda, complete with all the mad lighting, cops on the road, a Ron Boise sculpture looming out of the woods, and all the big speakers vibrating with Bob Dylan's "Mr. Tambourine Man." It was a very electric atmosphere. If the Angels lent a feeling of menace, they also made it more interesting ... and far more alive than anything likely to come out of a controlled experiment or a politely brittle gathering of well-educated truth-seekers looking for wisdom in a capsule. Dropping acid with the Angels was an adventure; they were too ignorant to know what to expect, and too wild to care. They just swallowed the stuff and hung on ... which is probably just as dangerous as the experts say, but a far, far nuttier trip than sitting in some sterile chamber with a condescending guide and a handful of nervous, would-be hipsters.

Indeed ... but no sand this time, so the lever goes up into fourth, and now there's no sound except wind. Screw
it all the way over, reach through the handlebars to raise the headlight beam, the needle leans down on a hundred, and wind-burned eyeballs strain to see down the centerline, trying to provide a margin for the reflexes.

But with the throttle screwed on there is only the barest margin, and no room at all for mistakes. It has to be done right ... and that's when the strange music starts, when you stretch your luck so far that fear becomes exhilaration and vibrates along your arms. You can barely see at a hundred; the tears blow back so fast that they vaporize before they get to your ears. The only sounds are wind and a dull roar floating back from the mufflers. You watch the white line and try to lean with it ... howling through a turn to the right, then to the left and down the long hill to Pacifica ... letting off now, watching for cops, but only until the next dark stretch and another few seconds on the edge ... The Edge ... There is no honest way to explain it because the only people who really know where it is are the ones who have gone over. The others -- the living -- are those who pushed their control as far as they felt they could handle it, and then pulled back, or slowed down, or did whatever they had to when it came time to choose between Now and Later.

But the edge is still Out there. Or maybe it's In. The association of motorcycles with LSD is no accident of publicity. They are both a means to an end, to the place of definitions.

As for LSD, I highly recommend it. We had a fine, wild weekend and no trouble at all. The feeling it produces is hard to describe. 'Intensity' is a fair word for it. Try half a cube at first, just sit in the living room and turn on the music - after the kids have gone to bed. But never take it in uncomfortable or socially tense situations. And don't have anybody around whom you don't like.

When the light turns green, you go. When the light turns red, you stop. But what do you do when the light turns blue with orange and lavender spots?

There are two major products that came out of Berkeley: LSD and UNIX. We don't believe this to be a coincidence.

Myths and legends die hard in America. We love them for the extra dimension they provide, the illusion of near-infinite possibility to erase the narrow confines of most men's reality. Weird heroes and mould-breaking champions exist as living proof to those who need it that the tyranny of ''the rat race'' is not yet final.
