The rumble of motorcycle engines filled a rainy morning in Washington on Sunday as thousands of bikers paraded around the National Mall for the 30th annual Rolling Thunder rally to raise awareness of US military personnel who went missing in action.

Participants, many of them US war veterans astride the loud, muscular Harley-Davidson machines typical at such events, rode into Washington led by a police escort over the Memorial Bridge, where cheering spectators waved Americans flags in support.

"I'm here supporting all veterans. My grandfather, my mother, and my father were all vets," said Kristina Harris, who was riding with about 500 members of the Nam Knights of America Motorcycle Club.

Harris captured the ride via GoPro on her helmet, documenting the motorcycles along the National Mall.
