In this May 26, 2011 photo, Randy Matthews, background, carries a piece of tornado debris in Piedmont, Okla., past the door of the tornado shelter where his mother, Betty Matthews, not pictured, stayed in safely during Tuesday's deadly tornado. The old-fashioned storm shelters that once dotted yards across the Plains have become relics of the past as home buyers invest in other features, like extra rooms, or try to save money. But violent weather is prompting some homeowners to give the shelters a second look. (AP Photo/Sue Ogrocki)
