One of the more than 400,000 motorcyclists who participated in the 17th annual Rolling Thunder "Ride for Freedom" to the Vietnam Veterans Memorial in Washington, D.C., breaks down after finding the name of a fallen comrade etched into the black marble of "The Wall." Officials are seeking photographs of the more than 58,000 men and women whose names are on the Vietnam Veterans Memorial for display in a new education center that is being planned.
