Somebody had to figure out how to put in the first path. Then it the trail was updated and perhaps improved. Maybe another individual found a better route. Eventually, a group decided to construct a road. It was not easy, but now buses, cars, and cyclists pass without considering the obstacles.
What paths have you blazed or improved? What is their impact? Does anyone notice anymore? If they are well-designed, perhaps the purpose is not to point out what was near impossible during construction.
