Maybe I'm missing something, but...

No offense to the author, but what kind of survival experience is a 6 hour stint? Even the full 48 hours only requires you find your way. Perhaps if I was deep in enemy territory, getting enough food would be more important than traveling quickly, but in this exercise I would have simply started hoofing it and gone hungry.

The points he makes are valid, but the anecdote seems lacking in survival challenge. (though, again, maybe I missed something)
