There are some very beautiful places in Wyoming such as Yellowstone National Park. You can buy almost any kind of fireworks there, and if there is a speed limit, its barely enforced.
Since there is less than half a million people there are very few cities. The few main ones being Cheyenne, Casper, and Powell. Wyoming is one of the few states still inhabitated by 'real' cowboys who catch rattlesnakes and ride horses around in tight pants.
Over all, because Wyoming has very few people and even less reasons to visit, it is seen as a boring, baren, uninteresting land. This is untrue.
Wyomingite: Um, Wyoming.
Local: I don't know why, but I live in Wyoming.
Out-of-stater: Oh, is that near Sydney?
Local: Nope, it's in East Dakota.
Out-of-stater: Oh. Still don't know Whyoming.
Local: ... Why Wyomin'? Because Wyomin' ain't fer everbuddy.
