We are traveling to Galena, IL this summer and I'd love to avoid Chicago.We don't mind interstates, but want to avoid as much city as possible. How bad is Indianapolis? Bloomington? I know some of you live or travel in the mid west. We've never been farther than South Bend,IN and that was 15 years ago. Traffic here has grown worse so I suspect out there it has, too. Thanks for any help or suggestions. We plan to take 2 days to travel.
