Rockford to Bloomington-Normal: An Epic Illinois Road Trip Guide

Between Rockford and Bloomington-Normal, Illinois, lies a direct shot down Interstates 39 and 55, a 140-mile corridor that defies the state's reputation for pancake-flat monotony.

I’ve driven this stretch dozens of times, and I’ve learned that the real adventure lies in breaking the cruise control and exploring the small towns and natural areas tucked just off the exit ramps.
