Rolling Thunder Motorcycle Ride Rumbles Through DC

Thousands of motorcycle riders participating in the Rolling Thunder "Ride For Freedom" line up in the Pentagon parking lot on May 29, 2016, shortly before parading through Washington. The annual Memorial Day weekend event honors military veterans and members of the military missing in action.

Staff Sgt. Tim Chambers kisses his bride Lorraine Heist during the Rolling Thunder parade. Chambers has become a fixture of the parade, earning the name "The Lone Marine," as he stands each year at attention to salute the passing bikers. No longer "lone," Chambers was married in a ceremony just before the start of the parade.

Riders cross the Arlington Memorial Bridge in Washington.

The Ride for Freedom only takes about 20 minutes from start to finish, but the massive amount of motorcyclists taking part in the ride shuts down roads for almost four hours.

Spectators wave to riders.

Rolling Thunder spokeswoman Nancy Regg estimated Sunday's event drew about 5,000 people. Above, a rider wearing a horn decorated helmet participates in the event.

People watch as Republican presidential candidate Donald Trump addresses the Rolling Thunder rally. Trump, who has a loyal following with bikers, told the crowd that the government often takes better care of people in the U.S. illegally than the nation's military veterans.
