i went there when i was 13, and i got the rookie membership. i think it was only $50.
it was a lot of fun, but for some reason i like completely forgot how to ski over that summer, so it wasnt as fun as it should have been. i kinda wish i could go back now that im better to learn some new stuff, but i cant afford it.
and to the kid who said its mostly mogul skiers- thats true but it doesnt really matter. plenty of freeride kids go too
as for the jump having the hydraulic top, there are 3 settings, top down, freeride, and aerials. top down is the smallest it goes, but you can still get pretty big off it. freeride the top is up, but it doesnt get any steeper than top down - the takeoff is just longer. and aerials they make it a little steeper, so you boost even higher, but its got more of a feel for aerials jumps.
