I recall hearing stories of fisherman and/or hunters that were flown into remote camps to be picked up in a couple of days.
Okay - sort of bad weather, we’ll wait another day.
After a few more days they start to wonder if their plane crashed on the way in. Do we try to hike out. Etc.
That is exactly what happened. They were dropped off, to be picked up on date certain, but no planes.
I don’t remember all the details, but we had to get some special exemptions to get folks home. Not very many roads up here.
