Chief cycles through cancer
U.S. Air Force Chief Master Sgt. Leroy Cooper, chief controller for the 509th Operations Support Squadron, takes a break during a ride through Knob Noster State Park, Mo., Aug. 22, 2013. While undergoing proton beam therapy for prostate cancer, Cooper used cycling as a way to mentally deal with his situation. Throughout treatment, he accrued more than 1,100 miles and just one week after being declared cancer-free, rode in the world’s oldest, largest and longest bicycle touring event.
