I think perhaps just a bit of forum jargon is intruding here...<br><br>Most of the time I think that we are talking about a small package of items when we say "PSK" - a candy tin, a tobacco tin - something that fits readily in a pocket.<br><br>"EDC", or every day carry, includes other things we carry - perhaps a PSK is part of ones EDC.<br><br>If I am deliberately out-of-doors, I will have those things and more with me. Four weeks unplanned could be very difficult or a lark, depending on many things. But if I were transported from my present work environment to a "use what you have on you" 4 week sojourn, it would be a very difficult situation.<br><br>Is your 4 week figure arbitrary or is there some situation that you conceive of that would merit a 4 week stint?<br><br>Regards,<br><br>Tom
