Oddly enough, Subarus sell pretty well out in Montana. My brother lives in Missoula and you see a lot of Subarus and full-size pick ups parked in his neighborhood.
It's been suggested (mostly by Montanans living in the eastern two-thirds of the state...like me) that the area around Missoula, Kalispell and Bozeman has been so overrun by California/Oregon/Washington interlopers that we may as well secede and let them go starve to death in the damn dark along with their buddies in the Sierra Club.
As far as the parks are concerned, both Yellowstone and Glacier have been plagued by no-brainer tourists for as long as they've been around. I recall thirty years ago that there was a regular radio station program in the Kalispell area featuring the Latest Stupid Tourist Tricks at Glacier and in spite of the park's relative isolation at that time, the program never, ever repeated itself or ran out of absolutely mind-blowing material.
I wouldn't waste my time or money going to either Glacier or 'Stone.
Guess I just never have lightly suffered idiots.
