Well, there's a great survival message there, "If you go into the desert, bring water". There's just no way to survive if you don't.

I did think the end was a little ambiguous, almost sounded like he was going to walk that couple hour walk to his safety crew himself. That would just be suicidal after two days with out water. It would have been good to point out that although the safety camp is only a few miles away it would be very easy to die trying to get there. But all in all I really enjoyed the show. Its interesting to see what you can and can't eat, scorpions yes, millipedes no.
