Vietnam veteran Jim Barbour shows off some of the arrowhead chipping he's found over the years hiking around the open spaces near his home in Killeen, Texas, which he has lived in for 38 years, Feb. 22, 2014. Barbour, a former Staff Sgt., was a door gunner in the 68th Assault Helicopter Company and logged more than 3,000 flight hours in Vietnam from 1966-1969. He received the Purple Heart for wounds he suffered when an enemy round hit his M60D machine gun during a mission in 1967. (U.S. Army photo by Sgt. Ken Scar, 7th Mobile Public Affairs Detachment)
