Survival Food Bars Comparison Review Part 1: The Why?

This is part 1 of 2 about emergency food bars. I recently purchased Mayday food rations, SOS food bars and Datrex food bars to see which one is better and talk about why you might want to keep some with your emergency supplies. Part 1 is about how they compare to other shelf stable foods and their pluses and minuses. Part to is opening and testing them.
