To me PSK is to keep me alive for 5 days while sitting tight awaiting rescue. I don't need as much protein as a hook caught fish to see me through 5 days, nor will a ripped pair of pants bother me all that much. Don't get me wrong, when I go into the "woods" I take my fishing kit, and usually lots of other things I don't exactly need in order to survive, but none of those non-necessary things goes with me everywhere, and so they don't go in my PSK, but in my backpack.
