When my son's freind came to visit from Seattle we decided to visit a different resort each day. We did Keystone, Copper, Breckenridge, and A-Basin. At the end of the week his favorite; the one he wanted to go back to was A-Basin. The terrain was awesome, the snow was great. We never waited in a lift line and didn't have to worry about crowds on the mountain. There is no better place to take a lesson either. The classes are small and the instructors are well trained. This truly is the locals' secret for very good reasons. A-Basin even allows you to use a Vail resorts pass on their lifts.
