Charles Toplikar Jr., a Boy Scouts of America Troop 31 boy scout, spaces out signs to be painted May 12. Toplikar aspires to be an eagle scout, and must complete a community project to be eligible. The signs, courtesy of the 633rd Civil Engineers Squadron, display mile markers and directional arrows for the Air Combat Command running trail on Langley Air Force Base, Va..
