Sign Assembly
Senior Airman Edward Diaz, 28th Civil Engineer Squadron structure journeyman, and Tech. Sgt. John Gines, 28th CES structures craftsman, verify that their work is completed to all specifications at the Rushmore Center on Ellsworth Air Force Base, S.D., Jan. 5, 2011. The leveling and spacing on the finished sign must be perfect to present a professional image. (U.S. Air Force photo by Airman 1st Class Zachary Hada/Released)
