Hamilton County, Illinois

Hamilton County is a quiet corner of southern Illinois that most people never think about. McLeansboro is the county seat, a small town with a big heart. It’s farm country, with plenty of corn and soybeans.

The population has been shrinking for years, but the folks who stay are stubborn in the best way. There’s an old courthouse square that looks like it’s frozen in time.

The county fair is still popular every summer. Hunting is popular too, as deer season is practically a holiday. It’s flat as a pancake, making for some killer sunsets. People here don’t lock their doors much because everybody knows everybody else.
