The story really shows some contradictions. No doubt they went off unprepared and seem to have made some foolish decisions along the way. Yet, after the jeep rolled, the Dad made some very good decisions and came up with an innovative solution.
One story says that they were "only" 4 miles away from "civilization." I can really envision the temptation to try to "go for help." But he made the right decision and stayed put.
He also built a fire, using the spare tire to support the fire and heat rocks, which he transferred into the car. Another good move.
We tend to focus (properly) on planning, equipment and preparation, but the most important thing is keeping your head and making good decisions and making innovative use of what you do have.
Now, all we need to do is get this guy on board with us and get him a proper kit for his jeep. . . and to do some prior planning!
