There are many motorcycle meetings in America. Motorcycle meetings can be found in almost every state. Some are held by local riding groups. Others are held by motorcycle makers and their fans.
The Sturgis Motorcycle Meeting is held in South Dakota. The meeting lasts a week with concerts, races, charity rides and other activities. The first event was held on a single day in August of 1938.
The United States also has other big motorcycle meetings. The Bike Week in Daytona Beach, Florida, takes place during the first full week of March and lasts three days. The meeting began in 1937. Early races took place on the beach. Bike Week also includes concerts along with rides to raise money for charities. Riders say that one of the highlights of Bike Week is riding down Main Street in Daytona Beach. People usually go to see very kind of bike—from old ones with the paint worn away to beautifully styled new ones
The Iron Butt Meeting takes place every two years. Riders must travel more than 1,400 kilometers over an 11-day period. They can then earn points by arriving in certain areas within a certain period and by visiting additional places in between. The Iron Butt Association says that the meeting is not a race, but a test of strength and riding skills.
Another meeting is called Rolling Thunder. Thousands of riders gather in the nation's capital each May to show support for current and former members of the military.
