Only places I've been this year are Whistler, Snowmass, Copper, and Stevens, all were good.
Whistler: Didn't hit Blackcomb one but the Whitstler one was really fun.
Snowmass: Well built, really fun
Copper: didn't really hit much of the Copper park
Stevens: My home mtn. really cool layout, fun to hit, a bit too flat sometimes though.
