Emily and Will, a couple from North Carolina, have a problem Emily says she's been losing sleep over—for the past two years, Will has slept outside every night, of his own choosing. "There he is sleeping on the screened-in porch in 17-degree weather," she says.

Will says he loves sleeping surrounded by the sounds of nature and the sounds of a babbling brook. "I had dreams of hiking the Appalachian Trail, and that's not going to happen anytime soon, so I brought the trail to my backyard," he says. Will even goes to the bathroom in a bucket outside every night.
