If you are coming from the the West / North West (NW of I80 & I39) at or above about Lattitude 41 degrees North, there is a good liesurely way to skirt the race track around the SW corner of the Chicago/ Lake Michigan.
As soon as I get an old write up cleaned up I will post it. If you can't wait email me at email@example.com. Essentially south side of Kankakee river to Kankakee then to IN 14 and US30 strait east to Lima. I live right on the route in Indiana.
