On Thursday, May 23, 2013 Sherry Wells stands near the storm shelter where she took cover when a tornado destroyed her home on Monday May 20, 2013 in Moore, Okla. Wells said she and her husband won a lottery draw to receive a government-subsidized rebate to install the storm shelter. A contractor finished work on the concrete bunker beneath the slab of their garage about three weeks before the tornado hit. (AP Photo/David A. Lieb)
