Nonsense! You would get plenty done and you would get to ski/climb whenever you want. I've heard so many people say that over the years. (Don't take offense to the following, you are a cool kid Walker) If you don't have the self control to balance life and school you probably shouldn't be going to college. I had class this morning and I climbed the Bastille this afternoon.
Close to home is a viable reason I suppose, but a few years from now you probably won't want to be living close to home anyway.
Also, aren't you coming up to Colorado this weekend? I think there is a reasonably good chance of a party at A Basin on sunday.
