Washington (CNN) -- The parents of missing U.S. serviceman Bowe Bergdahl led the Rolling Thunder ride in Washington on Sunday, trailed by the roar of what was estimated to be hundreds of thousands of motorcycles.
The annual Memorial Day weekend ride, now in its 25th year, is held in remembrance of prisoners of war and those missing in action.
Bergdahl, a 26-year-old army sergeant, was captured in Afghanistan in 2009 after he finished his guard shift at a combat outpost in southeastern Paktika province.
"Bowe, your family has not forgotten you, your hometown has not forgotten you. Your state of Idaho has not forgotten you, and thanks to all of you here today, Washington D.C. has not forgotten you," his father, Robert Bergdahl, told a cheering crowd.
