Kind of interesting.
I think I’d like to live in the frontier. That section including Montana that doesn’t seem to belong to a city.
At first WAG, I'd suggest that "frontier" area is:
1. Major coal/oil/natural gas production.
2. Constitutional Open Carry.
3. Tons and tons of veterans/gun owners/hunters.
4. Most of our land-based Strategic Missile launch facilities.
(Altogether, if I were a Globalist weeny at any level, I'd call it a No-Go zone.)
