My wife and I talk about this all the time. Nowhere in America, save Hawaii, could be better. (We don't want to move to Hawaii for a few reasons, but cost is the big one.)

When it warms up from climate change, Alaska might be in the running, but I think we're stuck unless we want to leave the country.

(I came from Colorado, btw - 20 years there - it's great but.. it's not as good. Mainly because we're green, they're brown.)
