Will County, Illinois
Will County sits on the edge of the Chicago metro area. Joliet is the county seat, and this gritty river town is working to reinvent itself while growing fast. Interstate 80 and I-55 cut through the county, bringing a constant flow of truck traffic.
Cornfields are giving way to subdivisions and strip malls. The county has a mix of old industrial areas, gleaming new warehouses, and patches of prairie all sharing the landscape.
The Des Plaines River winds through the county, creating some nice scenery along the way. Midewin National Tallgrass Prairie offers a glimpse of what Illinois looked like before the plow.
