I've got a roundtrip from Louisville to Pittsburgh planned in early November. I've pretty well plotted the drive up (through eastern KY, WV, and then up through SW PA--all interstate because I have to do it in one day), but I'd really like to get off the interstate on the way home, particularly between Pittsburgh and Cincinnati. I'll probably pick up I-71 near Cincinnati for the rest of the trip home.
I'm really just looking for a nice drive on the surface roads, with scenic spots, interesting small towns, historical tidbits, or just a nice place to pull off the road and stretch for a bit being nice bonuses. I have to get from Pittsburgh to Louisville in one day, so I can't venture too far out of the way.
Open to any and all suggestions!
