This is a picture of a trail promotion aid. It's a 6 mile polygon around the Road Fork Section - Buckeye/ North Country Trail. While there is no formal standard as to how to determine the trail's adequacy, if a thru hiker can sustain about 15 miles per day in the south of Ohio, then they should have to travel no further than 3.0 miles from trail to reach an amenity. If during trail promotion, we get an offer for a campsite, or resupply for example, the address could be input into a smartphone app. When the result returns, if it's inside the polygon, then it's relevant to those of thru hike abilities.
The idea here is to hope that we stumble across an opportunity to break up the northeastern 1/3rd of the section with another campsite. The reason is that the campground at Wolf Run SP to the shelter in the middle of the image is 19.8 miles. I've done it and known others who also have. That territory is hilly and it's at the end of most hiker's stamina here in Ohio. It can be a bit of a struggle to get there.
I discovered the remnant of a former railroad right of way in Caldwell of Noble County. I have no idea who it belongs to, but since it was nice and straight, I took a measurement of it, then got directions from the trail to it and added their mileage... it added 0.1. I've tried every way I could to try and and shave 0.3mi off of the distance from Road Fork Section to the Greyhound affiliates at the Caldwell Park-n-Ride. Bringing that distance from 3.3mi to 3.0mi or lower is not possible. There's just not enough coaxing that I can do to get it down. This one might bother me indefinitely.
