There's a guy that travels around on foot with mules and apparently brings attention to how this used to be a commonly accepted right to travel on a lot of roads, and now they're trying to restrict access to cars only in certain places without creating travel routes for people on foot, by horse, by bicycle, and so on, so he's filed a lawsuit over it to bring attention to the issue.
Whatever is to be made of it, he's engaged in an interesting experiment of travel and living outside nomadically.
