The Ozark Mountains are beautiful, and the cost of living is cheap...it's backwards though and very low tech in general, but very beautiful and some very friendly people. For the most part I grew up there...had to move though as it didn't feel like home to me.<br />
The Appalachians are even more beautiful, but I didn't spend much time there so don't know much more than what I saw on my way through...but I can tell you there's at least three amazingly great people in Kernersville NC there that saved my butt when my van broke down :-)

Southwest Colorado, has a lot of little towns in the Mts. that are very remote but not far from civilization. The woods look like scenes from Bonanza...
The White Mountans in Arizona are nice.
