The most consistent and excellent snow and skiing in the United States. I don't hate boarder's, but I don't miss them, it adds to the "Skiing the way it used to be". Most of the best skiing requires a little effort and know-how to find, which also adds to the appeal. If you're a serious skier, and you had to be stuck at one resort for the rest of your skiing life, this would be a good place to be stuck.
