The cave Sleepers May 18 2009
The Sleeper family in Festos, Mo., have given themselves over to cave living. Their home sits in a 17,000-square-foot cavern left behind from sandstone mining in the 1930s. The front of the three-bedroom home is taken over by glass to let in natural light and insulation helps keep the interior between 65 and 70 degrees year-round. Falling sand can be an inconvenience, but umbrellas help to keep the dust from living, eating and sleeping areas.
