Almost all of them say no cameras. Wedging a compact camera down the small of your back, is a good place for it.
Just don't forget if you go to the bathroom.
FYI, Chicago says NO CAMERAS..... yeah, I'm going to sneak one down my boot and we'll see what happens
And you know what Budred, I can't remember what show this was at, but someone brought in a professional camera. I thought, no way in hell they are letting them in! Sure enough, they got in! I thought, OK must have a press pass.... noooooope! I swear it depends on the venue and possilbly the artist as well around here and maybe security whether they want to bother or not.
