If you make it out to the small town of Seymour, you might notice a running theme. The hamburger. In 1885, the first hamburger was made by Charlie Nagreen. At the Seymour Fair, he flattened a meatball and put it between two slices of bread. Every year for one day, there is a Hamburger Festival. Here, the world's largest hamburger (5,520 pounds) was made.
