I've been to a couple of shows, and I've seen a couple of moshes. Never at the more more expensive venues like the nokia theatre and hammerstein ballroom( I'm in NY btw). But you know those $10 shows with 2-3 random openers and that 1 indie band that you may have heard of somewhere before.....maybe. People there don't seem to care if they look like idiots....its fun to watch at any rate.
