Mountain Breather 

People who live in N.H. or M.E. mostly lumber-jackers, or hill-billies. Mountain beathers can't afford good dental services, and have to drive three hours on dirt roads to get to their destination. Nobody comes to visit them, because nobody can find them, way up high in the mountians. Mountain breathers, are enviormental and ride tractors and go hunting for their food.

Ex: a mountain breather is someone with overalls and suspenders. Someone who doesn't know a thing about political statuses.
