Casper is fine. Do not make waves. Do not assume that because people are friendly, they aren't just busy body assholes. Casper has 1000% the customer service and neighborliness of small town Wyoming. Casper has work, and there are actual eligible young women who are remotely physically fit, so you can do stuff rather than just go to rodeos and watch other people do stuff.
Casper has a HARBOR FREIGHT STORE!!! A BIG ONE, not the little kind.
Casper is far enough inland that you cannot reach Colorado (so you can't get any more work or the pretty women from Colorado if you're young and eligible and working.) Casper has some cultural life, and it isn't quite the cesspit Cheyenne can turn into now and again. Again, its in the middle of nowhere, though. Its not a major political hub, the way Cheyenne is. Its also not a nuclear target, since Cheyenne gets that one all by its lonesome little self.
Both are downhill from the Caldera, so you get buried in liquid rock if things go bad... geologically speaking.
All I know is that if I had a choice of places to live again... "in Wyoming only," I'd say the hell with small town life and head straight for Cheyenne, Casper or Laramie. The more people from the outside flow in and out, the better life is. You don't realize how bad "conservatism" is, as a life philosophy until you live in a town where you aren't one of the in crowd, you better have work elsewhere.
