Thirst

The right decision would have been to backtrack at the point where the vehicle left the road. Why head elsewhere to unknown territory when all they had to do was keep walking on the road until hopefully a vehicle would show up? Then again, there would be no movie and all the suspense. I watched the movie and did enjoy it but after even one day hunger starts to set in and with the intense heat and no proper attire e.g. the women then would have been sunburned and totally exhausted. Doubt that the baby would have survived under those conditions. Where was the movie filmed as the area was so desolate and scary? It was risky for Noelle to attempt what she did on Jennifer when there was no medicine or sanitary conditions available. That was not believable.
