My understanding is it is legal for planes in Alaska to just land on a road. They have relatively few roads and many places are only accessible via plane, boat or some other alternative to cars (like dog sled) for at least part of the year. They have about six times as many pilots per capita as the rest of the US. Some of their little towns have amazingly minimal airport amenities and crudely constructed landing strips.
I sometimes post articles related to that but there seem to be relatively few good articles on that subject per se. Instead I end up posting articles sort of related, like where a small Alaskan community called everyone to show up with their vehicles to provide impromptu landing lights for a medical evacuation after dark when the lights were not working.
