Seward, Nebraska, claims to contain the world's largest time capsule. The capsule was started by a man named Harold Davisson, who apparently really liked the year 1975 because he had a 45-ton vault built to house all of the era's memorabilia. The collection contains around 5,000 objects, including a car built the same year, and it sits below a pyramid structure. However, the town is also known for something else.
It's been named America's Fourth of July city, and every year the small town of around 7,000 attracts 40,000 visitors for its annual Fourth of July celebrations.
