NW Ohio along the former US30, err Lincoln Highway. Very few cyclists in that part of the country and when I was on it last summer I was typically going 10 minutes in between seeing another vehicle or any kind. Watch out for some nice artwork painted on buildings as well. Quite a few communities have had a guy come in and paint murals on the side of buildings in their towns. Amazing the difference in traffic since the four lane went in. I was shocked at the lack of automobile traffic. I wasn't prepared for it. I am wandering about US30...I thought it went all the way across the country just like US20 and it was the first of the cross country highways.
