Franklin County, Illinois

Franklin County sits in southern Illinois, a place that can feel more like Kentucky than Chicago. Benton is the county seat, a historic coal town still working to find its footing.

Rend Lake is the big draw, offering excellent opportunities for fishing and camping. You’ll see plenty of pickup trucks and not many BMWs, while the local accent carries a bit of a southern twang.

There’s a historic jail museum that looks straight out of a horror movie. Coal mining has mostly disappeared, but its impact is still visible throughout the county. The Franklin County Fair is a major event, with demolition derby night always drawing a packed crowd.
