McGHEE TYSON AIR NATIONAL GUARD BASE, Tenn. - The sun rises over the freshly poured concrete pad on the ground floor of the new dormitory building under construction here June 22, 2015. Crews started pouring the pad in the early morning hours to allow the concrete ample time to set before the hot afternoon temperatures arrived. (U.S. Air National Guard photo by Master Sgt. Jerry D.
