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 or try to save money. (AP Photo/Sue Ogrocki)
