Me too, though all I experienced was the parking lot outside of the big arena, and a convenience store, where the owners said that the big crowds happened twice a year - the Dead and the Bills in the playoffs - and that they preferred the Dead crowd.
But the shorts-burning morons in the car next to us (who also tried to sell my skateboard) were from Boston, not Buffalo. However, there was one great incident where some big meathead guy was walking around with a homemade sign reading "free hugs."
