It was the (supposedly) helpful guy at the motel who suggested my route from Rockford IL, onto I-80 in IN..... I-90 >> 294 >> I-80.
Result was that it took me just on four hours to travel little more than 100 miles, despite starting at 6.30am.
Since I will be travelling this route at least twice more, could someone who knows the area please suggest a route to bypass Chicago.
I had originally planned to go down 39 as far as maybe 24, and then take that into IN and pick up 80 somewhere along the way. (I am unable to explain why I allowed myself to be talked out of that.) But there may be a better route.
Lifey who could not bear to drive through Chicago again
