Polar Plunge
Lanie Moreau hangs onto the arm of her father, Master Sgt. Jay Moreau, 90th Civil Engineer Squadron Emergency Management Flight, as they plunge into the icy waters of Sloan Lake, Cheyenne, Wyo. during the second-annual Matthew S. Schwartz Memorial Polar Plunge Jan. 4, 2013. Participants braved 16-degree air, and 30-degree water, temperatures to raise money for a foundation which helps wounded explosive ordnance technicians and their families. The event is named for an F.E. Warren Air Force Base, Wyo., 90th CES explosive ordnance technician who was killed in action while deployed to Afghanistan Jan. 5, 2012. (U.S. Air Force photo by R.J.
