A new highway sign in Lost Springs, Wyo., reveals a demographic shift. Drivers on Route 20 will notice the town's population seems to have quadrupled — from one person to four. Residents told the Casper Star-Tribune that the original sign — reading "POP 1" — was actually inaccurate. When it was put up, there were a full five people living there. So Lost Springs is actually living up to its name.
