Out California's Sonoran Desert lies a place called Salvation Mountain. It is a monumental work of outsider art, born of ecstatic spiritual convictions and built over many years by the late Leonard Knight. Since Mr. Knight's passing, volunteers have been working to preserve the site.

Adjacent to Salvation Mountain lies Slab City. Named for the ubiquitous concrete foundations left by the US Army when they abandoned the area, it's now a squatter's paradise. Everyone in this village lives here for free, and a vibrant offbeat community of artists, outsiders, street philosophers, snow birds, and burnouts commingle here
