U.S. Air Force Airmen and family members participate in a cardboard boat race in the base pool during the Heat Stress Awareness Extravaganza at Dyess Air Force Base, Texas, June 22, 2018. During the boat race, three teams competed against each other to see who could make it across the pool and back without sinking. The race was one of various activities held during the event to raise awareness on risks associated with sun and heat exposure. (U.S. Air Force photo by Airman 1st Class Susan Roberts)
