You Betcha.......When I'm planned to visit a new location to camp/fish I always contact the Chamber of Comm. Tell them what you're looking for and they forward that info to the places that will fit what you need. Your Mailman may not be happy with you for a few but you should receive plenty of stuff to pick from.
isnt Glacier National Park close to there.....im sure they have fishing/cabins. I know they have killer camping.....even if you just go to camp out there its nice.
