Vail = HUGE. Make sure to ride the back bowls, they are excellent and often icey, but when it dumps back there it is some of the best riding in the world.
I fractured my tailbone on a jump at Vail and the patrol staff did an excellent job. The snob crowd isnt that bad if you get off the front side on a weekday. Weekends here can be interesting, but Vail is so big it really doesnt matter when you go.
Vail = worth the money.
