An abandoned lawnmover is overgrown with grass in the yard of a decaying house in Monowi, Nebraska April 28, 2011. At its peak in the 1930's the town had 150 residents but after the railroad left it began its decline. Now down to a population of just one, Monowi is the only incorporated town, village or city in the United States with just a single resident. REUTERS/Rick Wilking (UNITED STATES)
