My Southern CO analysis
Purg:
I would go to Purg if I was with my girlfriend or family. Decent, yet unspectacular resort amenities, some of the best scenery in Colorado, and easy access to Durango. There is some good Tree skiing with some interesting drops and features spread out around the mountain. Not a Bad Place to spend a few days.
Wolf :
Never Been, but from what my impression is,you would go with some buddies for intense , serious pow skiing. No hot tubs, no bullshit, just Skiing.
