Since we try to be prepared for the unexpected, and being stuck for longer than 72 hours might be one of the unexpected things that happens, I feel that at least a minimal fishing kit has a good enough weight/space to possible usefulness ratio to warrant its inclusion in my BOB.

With that said, I carry approximately 25-30 pounds of stored fat with me at all times, so I could probably last for more than a few days without food. Yes, I tell people that my fat is part of my survival strategy.
