McDonough County, Illinois

McDonough County is tucked away in western Illinois, about halfway between the Mississippi and Illinois rivers. Macomb, the county seat, is home to Western Illinois University. There’s also some serious history here, with Abraham Lincoln giving speeches in Macomb.

The courthouse square in Macomb is a real throwback, with local shops and restaurants surrounding the old building. Outside of town, it’s all farmland, with corn and soybean fields stretching as far as you can see.

Winters can be cold, with winds whipping across the open fields and cutting right through you. But summers are gorgeous, perfect for county fairs and outdoor concerts. The people here are friendly, and it’s small-town America at its best.
