Second on Jackson Hole. I also like the Utah resorts. Never have been in A-basin to board; have mountain biked there but hear it’s awesome in winter.
I like Stowe better than Killington, but the whole atmosphere of Killington is nice if you’re up for a party. Long-ass drive to get there, though. If you can catch Killington during a storm, it is on par with a lot of west stuff. Normally, though, it’s too icy. I stay more at Pico than Killington a lot because it’s less crowded and has some good runs. They are supposed to be connecting the two soon so that should be cool.
I want to do Whistler/Blackomb. Hearing good things.
