House Built on North Carolina Landfill Has Sinking Feeling

Warren Salter’s yard had yielded more problems than dandelions. Just inches below the surface, he’s dug up glass, spark plugs, even the hood to an old truck. Salter bought his house in Havelock, N.C., in 2001, but by 2003 he realized that something was wrong. "Everybody’s yard is dropping," Salter told ABC News. "What used to be flat land for the kids to play football in is now big sunken areas."
