Doomsday Preppers

Deep in Oregon's backcountry sits an 80-acre off-the-grid estate that prepper Curt and his family have designed as a fortress in the event of an economic collapse. Isolation is one of their greatest strengths, but the protective measures are endless: a 3,000-square-foot greenhouse, a lake with 1 million gallons of water, infrared cameras and a high-tech software system — not to mention the children are trained in marksmanship.
