Uhhh, Kicking Horse, for one. With a fast gonola that takes you straight to the top. Now that the tram is gone in Jackson there's gonna be a lot more fucking around to get to the backcountry.
And if you think Jackson is great (which it can be when conditions are right, but GOD that endless sidestepping traverse out of Granite Canyon), you really need to try Europe or Las Lenas in Argentina. Most good Euro resorts make Jackson look like a bunny hill.
And I'd have to say that Silverton is better than Jackson and Telluride's backcountry is waaay better. Much less tracked out, and with a nice fast downhill exit on an old mining road. None of that fucking sidehill shit.
And you don't really spend the $$ you save on passes in other places on rent "in the end." The cost of living in Jackson is the same as other ski towns, especially if you want to live in Teton Village, next to the lifts. No matter how you cut it, Jackson's pass is one of the most expensive in North America.
