I'm not sure about the not having to worry about money portion, but I agree with the rest. It seems to be the 90's adventure sports crowd "settling" down and enjoying family life.
Instead, I think it's more the outdoor lifestyle, decent restaurants, at least a modicum of culture, maybe not retired-at-40 but comfortable financially. Especially if they're willing to trade the offerings of larger urban centers for a more laid-back, more outdoor activities oriented existence.
