Hey Bill, totally depends on the route you take back to Ohio and where you're headed. I reiterate the love for Forest Dunes--it's a couple hours from the Downs. It's not getting you much closer to your destination but it is a great golf course.
You probably drive through Ann Arbor as well and, if, being from Ohio, you can stomach that giant block M, the U of M golf course is solid as well as Barton Hills.
