If I understand correctly (and it's possible I don't) this should be the closest I could get to the northeast terminus of the Greenville Treaty Line on a public road.
The Tuscarawas-Stark county line from the other direction. I kinda hoped to see a historic marker for the Greenville Treaty Line, but no such luck.
There was more of the bicycle path along the Tuscarawas River between the county line and Bolivar. It was OK as far as it went.
