For Vietnam veterans, The Wall in Washington, D.C. still elicits vivid memories. National Park Service volunteer, Dan Arant, recently took these photos (edited by Donna Prince) on Christmas Day and on December 12th when the Christmas Tree Ceremony was held. Dan is also a volunteer at the National World War II Memorial. National Park Service Volunteers wear yellow hats and shirts while “on duty” at our nation’s memorials in Washington. We all benefit from their volunteer service and are grateful for their commitment to public service at these important sites.
