|Subject: Re: Outlet Malls enroute from Toronto to Chicago|
As a Chicagoan (originally a Hoosier) may I suggest an outlet mall in Northeastern Indiana - close to the Michigan border on Lake Michigan. Not sure if this is on your route, but it may be and it's worth a look see. The outlet is called Lighthouse Place Premium Outlets in Michigan City, IN. Here are the links to the information page:
Hope this helps a little bit! I think there are a few Chicagoans who are Ziners, so you should get plenty of suggestions!
