Missoula enrollment grew this year again, which is a positive. I think they're around 13K students now, was sub 10K not that many years ago. MSU has gained a lot of enrollment, kinda coincides with Bozeman's explosion in growth as well, plus investments in degrees that aren't horse shit unemployable degrees. UMs new'ish president is building that same kinda culture in Missoula, trying to get more STEM focused, esp in healthcare. UM would love to have a medical school, might be a thing in <10 years.
Rumor has it (though, I don't know if anyone has positively confirmed) that UM and MSU are tied at the hip. Couldn't tell you about UND/NDSU and SDSU/USD.. but man, I would have a -really- hard time believing that USD could ever make a move. UND prob has the best finances of any of those schools and I'd bet they'd never move up.
