the only muti mountain pass is north star/ sierra. the problem with that is these to resorts are very far apart, so if you live near one, you probably wont go to the other very much. I would prefer just buying one for a really good mountain like alpine, Kirkwood or squaw if you can afford it. which ever you live closest too should play a factor. then buy a cheap Boreal pass for a great park and pipe, and night riding.
Ride K2 skis!
