North Judson Mint Festival in North Judson
The North Judson Mint Festival began after a successful 1976 Bicentennial celebration led organizers to build a repeatable annual event around mint, a crop suited to the town's muck farmland soil. Now the second oldest of only three mint festivals in the United States and Indiana's only one, it runs every Father's Day weekend with a mint cooking contest, parades, bands, and food vendors.
Mint, not corn or wheat, put North Judson on Indiana's small-town festival map after a 1976 Bicentennial celebration went well enough that organizers wanted to repeat it the following year.
