I don't bring a "real" camera unless I plan on doing a pre or post convention trip, like I did at the Phoenix convention. I usually just bring a "point-and-hope", especially since you won't be as upset if TSA fries your P&H as you will if they fry your Mk3 (they fried my travel camera a couple years ago). I've hung merit prints that were initially captured with a P&H.
- it's not the camera, - it's what's behind the camera...
