McLean County, Illinois

McLean County is right in the middle of Illinois, often called the heart of the state. It’s the largest county in Illinois by land area. Bloomington-Normal dominates the scene. It’s an urban center surrounded by miles of farmland.
Corn and soybeans are everywhere you look. State Farm Insurance calls this place home so their headquarters is hard to miss. Illinois State University brings academics to the area. You’ll especially find plenty of cool spots to eat and hang out around campus.
The county has some serious history too. Lincoln practiced law here back in the day. The place comes alive in the summer. County fairs, outdoor concerts, you name it. It balances small-town values with big-city opportunities. Not a bad combo if you ask me.
