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.
Aside from the subject of food, we may not be all that much different in our approach. I do not carry a "PSK" in an urban environment. Rather I EDC an RSK, mini-Bic, Leatherman Juice, Photon, KelTec, and a few other items. No bandaids, needle and thread, scissors, etc. Sometimes I feel like the odd man out here but I have made my decisions based upon the problems I am likely to encounter. But in the mountains I carry what many--and almost certaintly you--would consider an excessive amount of gear.
I think it may all boil down to what we consider to be a "PSK" and what we do not. <img src="/images/graemlins/smirk.gif" alt="" />
