Vietnam War veteran Bob Maurer of Mercer will participate in the American Legion's Rolling Thunder ride to the Vietnam Veterans Memorial in Washington, D.C. Maurer has attended past rides and said one of his favorite parts is when a bagpiper starts playing at the site. "Everybody's walking around, talking, but when they hear the first note from the bagpipe, nothing. Nobody has to be told to hush," he said. "You don't hear any voices. Everybody's quiet and contemplating."
