From what I have read about the WY market in general (outside of Jackson), many come in unprepared for the harsh reality of mountain winters and lack of the level of services and entertainment they are used to (what, closest Starbucks is how many hours away?) and end up turning tail back out of the state. Do you see much of that in MT? I find it funny that people don't even do basic research. I've been to WY a few times (was just there in August), and I can see the appeal driving through it but that is in August.
I also noted the snow fencing along the interstates, and the gates at every ramp to the freeway in case that section of road is closed. "Gee hunny, why would they ever close the interstate?"
