I was at the first Bonnaroo music festival in Manchester Tennessee. Widespread Panic, The Dead (well at the time it was Phil Leash and Bob Weir), Jack Johnson, Ben Harper, Trey, Galactic, Moe, Les Claypool.
It was amazing! I'm not what you would call a "Hippy" but I really enjoy the jam bands. Not allot of people now a days make real music. I don’t think I have ever been offered so many drugs in my life though. The group I was with settled on some nice shrooms which were freaking amazing. I think I lost my mind a couple of times that weekend ;-).
One of the greatest experiences of my life. If you like music, like a laid back atmosphere, and can get away for a weekend in June, I recommend you check it out.
