The music festival I go to every summer is like that.
I've always been too fucked up to search, but my buddies have come up on a few things.
I was walking through a campground and saw this dude smoking purp from a Gandalf-style pipe, I mean it was like two feet long, and when I asked him where he got it, he said "I ground scored it from a picnic table". he was stoned, so I didn't go into how a picnic table is considered a ground score, but it was cool.
