I guess it depends on what you are used to. I mostly go to very small hippie festivals where people are overwhelmingly kind and considerate. I remember going to the 10,000 Lakes Festival for a few years in a row and as it got bigger you started to see more stupid shit - people cherrybombing outhouses and/or tipping them over, people wandering drunkenly down the highway, people yelling and screaming and generally being asses all throughout the campgrounds at all hours of the night. it's basically drunken/raging frat boy stuff. of course the trade-off is that you never get big names at the little hippie festivals - fat chance seeing M.I.A., Kanye or Gaga playing one of those.
I doubt I'll make it to Bonnaroo but I will definitely let you know if something changes! have fun and consider coming up to one of our little jam festivals
