Sorry to just defend it. Boca, its a generally nice festival, but being that it's without central organization, you may or may not like it. If you are expecting to go to a festival where all is provided for you, and some peace and love hippies want to hold your hand and chant, this is probably not the place. It is what you (and all others involved) make it. It's on public land, so everyone is welcome. If there is something in particaular that you want to see at a festival, don't have your hopes to high of seeing it unless you bring it yourself.
I think this is the major thing that mutant fest has lacked in the recent years. There are hundreds of people that arrive, hoping thateverything is set for them, and that the festival will just be handed to them. It's a free festival, open to everyone to MAKE what they want of it, not TAKE what they want from it. This year a large medical camp is being made after some unfortunate crap last year. This is the sort of initiative that makes mutant fest great. It's not centrally organited, but some people had a bad time last year, and this year, instead of going to rianbow, or just fucking off, they are attempting to make it better for themselves. these are the kind of people that need to go to mutant fest.
Otherwise you can generally find all types of people, cultural scenes, music, activities... From New Age Ritualist camps, to Acoustic Clown camps, to Black Metal Camps, there is a full spectrum folks to experience and share your time with. Read up on the website about what to bring. Don't come unprepared, making yourself a burden for the rest of the folks there, because there is enough drunk punk/crustifarian/drainbow bullshit to ruin the festival for a lot of people already.
