Birthplace of the hamburger in Seymour. Hamburger Charlie started flattening his meatballs and serving them on bread back in 1885. The first Saturday in August is Burger Fest with a Bun Run, burger tossing contest, ketchup slide, and stale bun stacking for the kids. They once grilled the largest burger that weigh 5,445 lbs and fed 13,000 revelers. The grill still stands.
