Kendall County, Illinois

Kendall County is the poster child for Chicago’s expanding suburbs. It was the fastest-growing county in the U.S. for a while, with cornfields giving way to subdivisions at breakneck speed.

Yorkville is the county seat, while Oswego and Plano are growing fast too. The Fox River cuts through the county, offering some green space among all the sprawl. You’ve still got farms out west, but for how long is anyone’s guess.

Traffic is getting worse every year as more people move in. The schools are good, which is why young families keep coming. The Farnsworth House, a famous glass box of a building, sits along the Fox River. Winters are typical Chicago brutal.
