It’s not exactly rocket science, not even close, but there are some things I take for granted while curious outsiders might have serious questions on why and how trails are built and maintained. I assume other builders are in the same boat, or maybe shoes is a better idiom to roll with. I also assume

Hyperacuity is our ability to discern very small angle differences and misaligned lines (see links below). Our vision doesn’t have to be good, and a vision test (visual acuity(sharpness)) doesn’t test this ability as the brain does a lot to amplify or help line things up or see misalignment. Sometimes I question whether I spend

Many of our roads and probably some trails were Native American routes in the past. I stumbled upon this guy who thinks he is finding and mapping old Cherokee routes. There is some info on trail marker trees here, and old trails here. More on Cherokee networks here.
