Earthships and off-grid living on Taos mesa

Taos, New Mexico is a strange place. Somehow the flat-topped mesa mountains outside Taos have become a mecca for alternative lifestyles with hundreds of people living off the grid. These people are not just hippies, there are all kinds of people from veterans suffering from post-traumatic stress to people preparing for the end of the world and others who are trying to escape or hide from society.
