Yes, but it is essentially in a field of grass. It did get a little crazy last year...but I don't think the police will tolerate that again. Someone lit a couch on fire (not sure how they got a couch in...) and some beer cans rained around late last year....
This time, on the Six Fest website, they are begging not to repeat Palmer as some proceeds are going to a charity. Also, they are not allowing you to bring furniture or glass bottles.
BTW it is $15 if you get your tickets in advance and $25 at the "door".
