i know its a pita but when these people stop showing up, ski areas pack it in. I got cut off at least 6 or 7 times over the weekend, and while it sucks, at least we aren't out there alone. once the paying customer stops showing, hills close regardless of how much snow is left.
Sad, but true. I'll gladly deal with a few morons from time to time if it means my local hill will stay open later.
