I'd suppose it's a development similar to (or exactly) gentrification. First a few pioneers come for the cheap housing, they make it cool, a few more people come for the coolness and eventually, if a critical mass is reached, it'll become an established desirable area (of course this can reverse as well). Since people tend to accumulate I suppose that once the prices in Bend get too high people will indeed spread out, bit one of the nearby towns will win the "trendy" people.
