Vietnam Veteran's Memorial
It's hard to be an active Harley rider and not encounter US military veterans. They make up a large portion of the Harley riding population. Organizations such as the Patriot Guard Riders (PGR) and Rolling Thunder combine enthusiasm for riding with support for veterans' issues.
A big benefit to riding with veterans is exposure to rewarding experiences such as the annual Rolling Thunder event each Memorial Day weekend in Washington, D.C. Twice I have ridden to Washington to visit the Vietnam Memorial, also referred to as "The Wall." I myself did not serve in Vietnam but nevertheless find the experience of placing my hand on The Wall and seeing the many gifts and notes people continue to leave for Vietnam veterans a very moving experience.
