I rather enjoy driving the US 35 corridor through Ohio.
I've only been on the WV to Chillicothe part, and once at that, but one thing I do remember about it was how scenic & hilly the section between Jackson and Chillicothe was. That's the most "mountainous" looking part of Ohio I can think of when it comes to what you can see from an expressway or freeway (compared to what I've seen on 23, 33, 77, 11 & 7 in other hilly parts of the state)
Found out that part of Ohio is where Bob Evans Farm is that started the Bob Evans sausage and restaurant company.
Really think that the Federal Government seriously need a better Interstate system between Chicago and the Carolinas. The current route is 100 miles too long, A Dayton to Charleston Interstate would really help truckers cut their time and costs. Maybe even create a new Highway from Dayton up to Chicago bypassing Indianapolis making the route even more direct. US 35 is almost done except when you get near Dayton there is an awful stop light section around Xenia and a really narrow, shoulder less very old Freeway in Dayton proper. West Virginia is also missing a chunk where its is two lanes and goes through small towns.
