Interesting fact #6 about MT from here.
#6. We Got Your WMD Right Here, Buddy.
If Montana were to secede from the union to become its own sovereign nation (and don't push us, man, we'll do it), we would instantly become the world's fourth-largest (known) nuclear power. Innocuous white concrete bunkers sprouted in fields and valleys across 23,000 acres of central Montana contain some 200 Minuteman III intercontinental ballistic missiles equipped with nuclear warheads and watched over by 55 "missileers" of the Air Force's 341st Space Wing. Don't mess with Texas? We've got three words for the Lone Star State: Bring. It. On.
Believe it or not, I already knew that, thanks to AWM and her (sadly) brief foray into the world of nuclear engineering.
