In a response to the Million Muslim March underway on Sept. 11, motorcyclists converged on the nation's capital for an event dubbed the "Two Million Bikers Ride."
Thousands of motorcyclists were meeting up in Washington D.C. to pay their respects to the victims, heroes and survivors of 9/11.
Organizers did not receive a permit to have traffic blocked, so participants were riding through streets in what was possibly expected to turn into an all-day event.
The bikers' exact route was being kept secret for security reasons.
Organizers were using social media to inform spectators where they could show up and cheer riders on to show their support.
