There's a great range down not quite to 3 forks. Go down to Yellowstone Gateway Sports in Gateway and ask about the range, they have the memberships there, you have to be an NRA member. It's like $40 for a year. It's a great range, it's a heck of a deal.
Yellowstone Gateway is a good place, there is also I think it's The Bullet Hole over off 7th, and he's got a nice little gun shop too.
MT is great, it can snow anytime. It can also be amazingly beautiful.
19th is a disaster and getting worse. Live close enough to campus to walk, shoudl be plenty of people subletting.
The pizza at Buffalo Bump in Gateway is amazing.
