In this Thursday, May 1, 2014 photo, Jacob Ortiz, of Thunderground Storm Shelters, directs as the finishing touches are put on a hole for a storm shelter installation in the garage of a residence in Oklahoma City. Last year's deadly tornadoes, which killed more than 30 people, scared Oklahomans in a way that previous storms had not, moving them to add tornado shelters or reinforced safe rooms to their homes. In fact, surging demand has overwhelmed companies that build the shelters. (AP Photo/Sue Ogrocki)
