Market 38, 12 photogs each photog has his own gear, we have 3 guys that take car and gear home. It helps with breakage a lot!! If your the only one using the gear and it's broke, well, guess who broke it. We have found that people take better care of the gear knowing that their responsible for it. Each photog has a car assigned to them aswell. Sports has their own camera, however, sometimes when two sports guys are out, they will take another photogs camera.
In other words, we are VERY lucky that we don't have to share. I've been there and done that.
