I lived between Bozeman and Butte for a few years, just moved this past August.
Winter there is much better than on the East coast. The temperature reads colder, but feels warmer. I've been outside in the sun on 20 degree days in a t-shirt raking leaves. I've been camping and woken up to 6" of snow on the ground, 30 degrees outside, and shirtless building a fire.
It didn't hit but 15 degrees here in WV once this past winter, mostly stayed in the 40s and we were fucking freezing and miserable for 3 months.
Bozeman is booming right now, and crazy freaking expensive. Don't move there expecting 40 acres and a cabin for 100k. You're looking at townhomes and condos in the 300s.
Montana roads are great. They plow them constantly.
Bozeman is very hippyish/skibum/snowboarder types. But it's a big city (for Montana, I mean it's no NYC) and there's anything you could want there. The even have an excellent Korean BBQ joint and one of the best Habitat Re-stores I've ever seen.
Not sure what kind of info you're looking for. I can't imagine SLC has anything Bozeman doesn't.
You'll love it there. I spent a summer in Livingston and went to Bozeman just about ever other weekend if I wasn't in Yellowstone or the general area. The main drawback to the area is that it is very isolated. I think the closest big city is SLC and that is a hike. But I am partial to areas like Whitefish/Glacier National Park. You'll need to head up the Going to the Sun Road in the summer.
You better be cool with cold ass winters too. I spent just a few weeks there as well in the winter, so you better like skiing and/or other winter activities.
Glacier... Glacier is something else. I was really blown away.
Best park I've seen now.
I spent some time in that park in the summer and winter. XC skiing there for a solid day in the winter and then staying at Isaac Walton Lodge. They had rail cars you could stay in over night. http://www.izaakwaltoninn.com/lodging/cabooses/ Lots of great downhill skiing around the area of course - we spent our time on the Big Mountain and Fernie just across the border in Canada. But Going to the Sun Road is really a must - it's gorgeous. And a great way to head up to Banff and Lake Louise.
How late is the road open? I didn't get a chance to see the Canadian side when I went up.
I'm really loving it out here. It's been an awesome move - I only wish I'd come sooner.
On a practical note, I found winter tires were a must buy. I drive the Gallatin Canyon a couple days a week, and it can get treacherous. We have Hakkapeliitta 9s on our work vehicles, and they've been fantastic. There are a couple of trucks with old Hankooks, and they just feel skittish were the Nokians feel planted.
I've got Hakkapeliitta 8s on my LR3, and they've been fine.
I've been going to Autostop in Bozeman for the things I can't do myself, it's expensive, it's one of those places that serves coffee and will drive you around town, but they've done a good job.
