Rolling Thunder

Every year on Memorial Day weekend, Washington D.C. becomes host to Rolling Thunder, a large motorcycle rally originally started by a group of Vietnam veterans. Thousands of veterans from around the country ride in on motorcycles to honor those who served, and remember those who were left behind. They don't come on small, quiet bikes either - they ride the loudest Harley-Davidsons they can find, to make Rolling Thunder live up to its name. You can see all sorts of motorcycles on the road all weekend, and the various riding groups all have unique logos and patches.

Many of the riders proceed to the Vietnam Veterans Memorial Wall to pay their respects. The Wall, designed by Maya Lin and embedded in the ground, bears the names of the 58,000 American service members who gave their lives in the war. One end of the Wall points to the Washington Monument, while the other points towards the Lincoln Memorial.

Many of the activities take place near the Lincoln Memorial, which has a lot of visitors at any time of year, but is particularly crowded on Memorial Day weekend.

On Sunday, the riders will gather in the Pentagon parking lot and ride slowly over the Memorial Bridge towards the Lincoln Memorial and the Wall. Previous events have had as many as 900,000 participants. The sound is not something you will forget.
