If I could only ski in one zone it would be Reno (REV). Tons of choices and lots of snow (usually).
If I had to live in one zone year around I would have 3 choices: Reno, Spokane (OTX), or Pocatello (PIH).
Reno has the Lake Tahoe ski areas and the area just south of Carson City (Carson Valley) would be a great place to live. It has great moderate weather year around, although it is expensive.
Spokane has a ton of ski areas also that are close and is more affordable than the Carson Valley, but the weather is not as nice. There is also the Powder Highway in Canada.
Pocatello metro population is small (90K) it is a bit of a wild card, but it has a nice local area 20 minutes from town (Pebble Creek, 2200 vertical, 1100 acres, 225" of snow). Pocatello is centrally located to Grand Targhee (2:15), Jackson Hole (2:45), Snow Basin (2:10), Powder Mtn (2:20), Sun Valley (3:00), Big Sky (3:30) and a handful of smaller areas within an hour or so. The weather is ok and better than Spokane.
If I was choosing an Eastern zone, it would be a tossup between Albany, Portland, and Burlington leaning towards Portland.
