Independence Day in the United States is celebrated every year on the Fourth of July. For most communities throughout the nation, the traditional celebration includes parades down the main streets, picnics with hot dogs and lemonade, and, of course, a fireworks display at night. In some towns across the country, however, special events are planned in honour of the occasion. In Bristol, Rhode Island, fire engine teams from communities throughout New England compete in a contest to squirt water from their fire hoses. Flafstaff, Arizona holds a huge three-day powwow, including a rodeo for twenty Native American tribes. The annual Eskimo games with traditional kayak races are held in Kotzebue, Alaska. Two auto races are always scheduled for the Fourth, including a four-hundred-mile stock car event at the Daytona International Speedway in Daytona, Florida, and an annual auto race up the fourteen-thousand-foot precipice at Pike's Peak in Colorado. Several small towns celebrate in other unique ways. Hannibal, Missouri, the hometown of Mark Twain, invited the children to participate in a fence-painting contest, performing a scene from Mark Twain's novel Tom Sawyer. In Lititz, Pennsylvania people gather in the Limits Springs Park to light thousands of candles and arrange them in various shapes and images.
