I don't know what the rules are but I know in the past they were quite strict on this. Again, it might have to do with insurance rules or camp rules, which I can understand, but it might be more generic reasons, food etc. Maybe it should be checked out and people should write letters if it is not for an infallable reason. I think it harms a camp if people can't come in and out depending on their finances, transportaion, other committments etc. They shouldn't be able to mess up the food count, but that is so easily solved by bringing own food, eating at a nearby restaurant (town is not far away). Also some people prefer motels etc. and they should be able to just pay a day fee and attend the camp, or their spouses etc. sometimes don't share our love for hard bunks. This is a generic observation, not just about Rainycamp. Camp organizers, keep this in mind. mg
