Well this is SO not a pass / flyer I own or anything - jerrygarcia.com actually, but it IS the concert after which my friend and I called acid rescue (yuppers, that's right) when we accidentally drove over the river to East St. Louis trying to get home after the concert... at which we bought purple microdot in the bathroom...
Peace!
For me? Yeah, one of my favorite GD images every time I see it...
