I moved to Alaska. While the official state motto is "North to the future" or some such drivel, more unofficially you'll hear (especially among those who've been here a while) that "Alaska is what America was." Guns are still unremarkable, everyday tools and necessities here . If they manage pass onerous and ridiculous gun laws here in Alaska, by the time we get to that point there will be nowhere left to go (or, to borrow more eloquenty from Tacitus, ". . . there are no tribes beyond us, nothing indeed but waves and rocks, and the yet more terrible Romans, from whose oppression escape is vainly sought by obedience and submission.")
That said, if I needed to relocate, it would be done with an eye to gun laws. My wife was considering a post-doctoral fellowship in Denver within the last couple months, but recent events in Colorado are such that we won't be living there, even for a couple years, unless the gun control stuff they're pushing falls by the wayside.
