Wasn't it awesome this year? (I'm trying to distract myself because I'm passing up a PRIME stoner opportunity because I'm getting drug tested, bummer)
I havent been. But someone I used to know went to the one that was here in Idaho awhile back. He said people will come up to you and tap you on the spine and say something odd (i forget what it was.. was new age sounding). And they had had LSD on their fingers. But thats all I know. And I'm sure thats not every case, just his story.
