I guess this was the mistake by the lake. Way over priced, the staff were a bunch of unfriendly washed up roadies. HA HA HA. Lots of things to look at, but not to much on the history of where the different styles came from. The grateful dead exhibit was really stupid, 2 floors for hippies, great!
Either way if you need to waste 2-5 hours, its a must, I would personally give a homeless person 30 bucks and let him kick me in the ball, at least someone would get their money worth.
