Retired Air Force Staff Sgt. Dennis Blessman speaks to visitors about the Moving Vietnam Veteran Memorial Wall after the opening program at Mission Springs Park in Desert Hot Springs, Calif., June 22, 2017 The Moving Wall, a scale model of the original Vietnam Veterans Memorial Wall, has the names of those men and women who were killed or missing in action etched onto a reflective stone, so visitors can not only see the names, but see themselves, reflecting on the lives of the people who fought and died to keep them safe.
