I just did a 3 day bike tour in north east Ohio (~200 miles). When I was slowly riding through a small village an Amish buggy passed me. That’s a first for me. Ohio highway 7 (near lake erie) is awesome. Low traffic flat roads and a reasonable shoulder. Youngstown sucked bigtime.
Youngstown was bad. I took south ave because it seemed like the easiest way through on the map. It was 5 miles of heavy suburban sprawl traffic (with a gradual uphill too). The worst bike experience I can think of (837 in duquesne might be #2).
