Aspen leads a double life. On one hand, the little Colorado town with the big reputation is a hotbed for celebrities, monster homes and racy nightlife. On the other, it's a haven for people who cherish fresh air, spectacular scenery and the outdoor lifestyle. The common denominator is the mountains. Aspen Mountain, Snowmass, Buttermilk, Aspen Highlands: together, they form a winter playground that doesn't care if you're decked out in ski couture, or your boots are held together with duct tape.
