Pike County, Illinois

Pike County hugs the Mississippi River in western Illinois, wedged between the Illinois and Mississippi rivers. Pittsfield, the county seat, is a small town with a big courthouse square.

This is hill country, a major contrast to the flat prairies most folks picture when they think of Illinois. The landscape is essentially a patchwork of forests and farmland.

Hunting is huge here, with deer season bringing visitors from all over the Midwest. The county also has more than its share of history. John Hay, Lincoln’s secretary and later Secretary of State, grew up here.
