Charles Toplikar Jr., a Boy Scouts of America Troop 31 boy scout, scrubs excess paint from one of his signs for the Air Combat Command running trail May 12. As a marathon runner, Toplikar ran the ACC trail on Langley Air Force Base, Va., often as practice, and became confused at multiple points. Placing the new signs for the trail allows runners to properly assess their distance. (U.S. Air Force photo by Airman 1st Class Austin Harvill/Released)
