The camera situation depends on the venue. Apparently House of Blues venues don't allow cameras at all, no questions asked (even if the band allows them). At The Rave in Milwaukee they usually never allow cameras either. When I arrived at the venue there was no security at all, other then the guy taking tickets and checking id's (for drinking wristbands). I guess they did start checking people right before the show started. There were no security guards on the floor by the stage though so you could have been taking pictures and no security would have seen.

That was actually the first time I've ever been to a concert at The Rave here in Milwaukee where they did not have a barricade up between the fans and stage.
