Can someone share a picture of an improved forest service back road?
Around my slice of Northern Michigan, a forest service road is a mud/dirt, not gravel, not aggregate road that winds its way through the forest. mainly providing access for logging or the PC term "stewardship", it also lets firetrucks get in to fight the occasional forest fire. Most are just two-tracks, some are well traveled enough that there's no grass patch in the middle of the lane.
Not my video, but this is a good example of a forest service back road in Michigan
