I dunno, I associate Yellowstone with Wyoming because that's where Old Faithful is, and that's the main thing Yellowstone is known for. Maybe it's just a geographical thing, but the only thing I know about Montana offhand is that it's the called the Big Sky State, the capital is Helena, the mascot for the University of Montana is the Grizzlies, and supposedly there are areas where there is no speed limit because of how few people travel there, but I don't know if that last thing is actually true.
It was true on all interstate highways in the state during the daytime for cars (i.e. not trucks) for a few years in the 90s before the legislature changed their minds.
