I would move to Colorado in a heartbeat, particularly to Boulder, for its recreational activities and the cycling culture there (you can live a full life without a car). I've heard tons of good things about it from proud residents. There are buses to the local ski area and to Denver airport and downtown. There are miles of trails all around the city. It's a biker's, runner's, hikers, and cross country skier's paradise. It's no surprise that real estate prices there are so high (also because the city has strict limits on urban expansion and development).
I hiked 450 miles along the Colorado CDT. Absolutely awesome, especially the San Juans and the Sawatch. They don't even have bear problems (yet...). I've climbed Pikes Peak, Longs Peak, and Elbert. Colorado rules! I want to go back.
Not only that, but the climate along the Front Range is mild enough even in winter to enjoy outdoor recreation.
I can't think of a better place to live in the U.S. for a dedicated backpacker, cyclist, IT geek, or tree-hugging hippy.
