Clark County, Illinois
Clark County sits on Illinois’ eastern border next to Indiana. Marshall is the county seat, which is a small town county with a friendly vibe.
The Wabash River forms the eastern boundary. Rolling hills break up the farmland. Lincoln Trail State Park is a local spot that’s also great for camping and hiking.
Agriculture drives the economy here. Corn, soybeans, and wheat are major crops. Oil wells pump in parts of the county which reminds us of past boom times.
