Well, I am flying back to Indiana next Thursday to visit Mom in Fort Wayne. I'm thinking we would both enjoy a trip to either Brown County or Southeastern Indiana.
One route I'm considering is to take US 27 to I-75 to Cincinatti, one of my absolutely favorite cities, then winding our way west along the Ohio River to Madison, then back up through Indianapolis and maybe Columbus, Indiana. I have Friday, Saturday, and Sunday totally free for roadtripping.
Or, we could just head to Brown County via Indianapolis. I enjoyed Broadripple, Brown county is cute, and I could hit Columbus (I'm an architecture nut).
I love Greek Revival architecture, and the leaves should be great next weekend, so Madison/Switzerland County/Cincinnati should be pretty nice this time of year.
