Staff Sgt. Raymond Zgoda, 28th Civil Engineer Squadron heavy equipment and pavement technician, removes a concrete curb during minor repairs in front of the 28th Bomb Wing Headquarters on Ellsworth Air Force Base, S.D., June 27, 2013. After the concrete and pavement are cut, the pieces are removed and the existing hole is then filled in with new concrete before being shaped to make a new, effective curb.
