Jan Manning, Fort DA Russell Days volunteer, hammers an 'S' hook into iron for a blacksmith demonstration at F.E. Warren Air Force Base, Wyo., July 19, 2019. These presentations allow visitors to feel like they’re taking a trip back to the early days of the base. The annual open house invites the community and visitors to tour the base to learn about its history and its current ICBM deterrence mission. (U.S. Air Force photo by Senior Airman Abbigayle Williams)
