This will be the most massive motorcycle run that you've seen. Thousands of motorcycles pass by giving tribute to American veterans of different wars. The history of this rally dates back to the times of the Vietnam War. It was first organised in 1988 to support servicemen that were left behind as prisoners of war. Since then the rally has become one of the biggest displays of American patriotism held annually during Memorial Day weekend. The most impressive spot to watch the rally is on Memorial Bridge. Then you'll see why the rally is called "the Rolling Thunder."
The Rolling Thunder "Ride for Freedom" usually starts at the Pentagon parking lot, then it passes over Memorial Bridge into North-West D.C. Bikers circle the National Mall and ends their ride at the Vietnam Veterans Memorial. The Rolling Thunder grew from 2,000 riders in 1988, its first year, to more than 500,000 riders in 2018. However, it's getting tougher to organize this ride with the growing number of participants and growing security concerns in Washington DC. The ride is held by Rolling Thunder Inc., the nonprofit group that spent about $200,000 to stage the event every year.
