It's one of the top 50 states in the United States.
But to be serious, where are you coming from, that would help us in finding out what you may already know about the area. (i.e. if you're coming from Alaska, we don't need to tell you about the cold winters)

Oh boy well Im coming from California. I know about the winter being pretty intense but Im used to the Summer there.

Well, it's way smaller in terms of population density. The largest city is Billings with only 100,000. Bozeman is roughly half that size. We don't have a sales tax, so that's pretty neat. I haven't really been in Bozeman that much, so I can't help you out with any specifics. Lewis and Clark Caverns are nearby and are a pretty cool place to check out, but I think they are closed right now.

Not living in MT currently, but born and raised there! Bozeman isn't big, but it's definitely unique! Great fishing, hunting, skiing (you're up in the mountains!). Montana State University is in Bozeman and offers a lot for a smaller college. Museum of the Rockies has one of the largest dinosaur exhibits in the world. You're a couple hours drive to Billings to the east, Missoula and Butte to the west, and south is Yellowstone National Park. Crime rate is far lower than CA, but be advised practically everyone there owns a gun (which is why).

Keep Californians out.
