In an effort to promote the mental pillar of the Comprehensive Airman Fitness concept among Airmen, the base will conduct a series of activities throughout the day at Ellsworth Air Force Base, S.D., Nov. 4, 2013. The objective for the upcoming CAF Day is to encourage Airmen to discover opportunities available in the Black Hills area, while also calling attention to potential safety threats Airmen and their families can face during the winter season.
