Great story! To me, being prepared, or equipped to survive, doesn't equal thinking that everything will unfold perfectly and nothing will ever go wrong. (It would be just as foolish to think that you were well prepared just because an adventure goes off without a hitch.) We should do what we can to minimize problems, try to anticipate and mitigate what we can, but things will go wrong. That's life.

Kudos to these guys for knowing what they needed to do to survive the situation, and for doing so successfully. A GPS and 2-way radio may have helped them stay on the correct course or get help sooner, but you know what we'd say about them putting their faith in technology if they didn't have the chops to be out there in the first place ... It sounds like they had decent supplies and skills, just made a navigation error.
