The Rolling Thunder motorcycles that descend on Washington every Memorial Day weekend made their final ride on Sunday, ending a three decades-old tradition that was initially meant to pay tribute to fallen and missing-in-action soldiers.
The veterans advocacy group, formed in 1987 by 73-year-old Vietnam veteran Artie Muller, got its name from a 1965 bombing campaign against North Vietnam dubbed "Operation Rolling Thunder."
President Donald Trump gave the group a shout out on Twitter on Sunday and pledged that the annual rides in Washington would continue.
