I'm at CU (sko)! There's a pretty big ski culture here. There are two teams that take up most of the skiers. The CU Freeski Team http://www.colorado.edu/sportsclub/freeskiing/
and Boulder Freeride http://boulderfreeride.org.
Most around here usually have the Epic Local pass, so they ride Keystone, the Basin, or Breck. The Rocky Mountain Super Pass is also a super good deal, with Winter Park, Copper, and Steamboat and Crested Butte if you feel like making a trip. I think this pass also has Eldora, which is like 25 minutes from Boulder.
Hope this was helpful! DM if you want some more info
