I remember such a case in Alaska where the only other airfield was many, many, miles away. It was years ago but this could be the same case.
Ah, yes.
King Cove to Cold Bay airport gravel road. Proof that white liberals think birds are more important than Native (human) lives.
Oddly, the bulk of the road now exists, from both ends.
Alaska public media has plenty of videos should you care to learn more.
