Yeah, I think the dogs are really just there for bombs. I've been to a few concerts where there was a lot of pot smoking being done. Specifically, there is a LOT of smoke at Jimmy Buffett concerts, hell that place was pretty much hotboxed. I've never smoked at a concert, though I've definitely smoked in the parking lot in my car just before going in (specifically at a Foreigner concert and a Stevie Nicks and Don Henley concert.
