We've all done foolish things. I'm sure some of us have nearly needed a rescuing. Short of a split leg, most of us have managed our way out without SAR. Of course, we're prepared.
We're prepared because we've used the search function here, asked questions, listened intently, and practiced. When I was taught that fire was hot, I did have to check that myself. Its fair to note, though, that I had the wherewithall and cognitive capacity of a two year old.
Those guys should have been of sense enough to know that its winter and that its going to get dark and cold. Life is a right until SAR teams must give you blankets to survive. "Live and learn" is a luxurious phrase.
