Sliding into safe sand
Airman 1st Class Justin Emanuelson, 319th Civil Engineer Squadron heavy equipment operator, maneuvers a tiller around the sandbox at the Child Development Center, May 7, 2013, on Grand Forks Air Force Base, N.D. The 319th CES works on the sand twice a month during the summer, or as needed, to prevent it from hardening and potentially harming children.
