The city of Horicon has grown beyond its mill town roots to become home to John Deere, Gardner Manufacturing, and many community events. Meanwhile, Horicon Marsh has loomed to the north with its own story to tell. Over the years, what was once the land of the Winnebagos has been flooded, drained, dredged, and farmed. However, thanks to a restoration movement that began in the 1920s, Horicon Marsh stands today as the largest freshwater cattail marsh in the United States.
