Beautiful place! Party at your place in a couple weeks?I may be in Missoula...
If you're going through Missoula take a detour and go down the bitterroot to Darby. You can see the now famous Dutton Ranch (the old Chief Joseph Ranch) where they film the TV show Yellowstone.
Backtrack a few miles to Skalkaho Falls and go over Skalkaho Pass to Philipsburg. Awesome little town. Go through Georgetown lake and end up in Butte Montana - make sure you do the underground tour in Butte the next morning.
