Not really sure of the bands. I didn't see a bill, and I am not real savy. There was a mix of jamb bands, reggae, some kind of agro rock, hip hop. It all depended on what stage/area you where in. We where there early in the afternoon and the music was getting better as the day went on. There was deffinatly ALOT of tokin going on. I did see one guy getting a ticket, but then realised he had an open intox. Not alot of po po, but there where a few. It was after all "give a cop a bong hit" day.
On the way out, I told some cops that I thought I smelled someone smoking some weed, and they just laughed. Awesome vibe all around.
