Lets think outside the box for a minute, or PSK. I became dissatisfied with my PSK medical supplies. I merely acquired a second container dedicated to First Aid essentials. The later input of Beachdoc and Trustbox inspired yet a second reappraisal of what I could and couldn't,should and shoudn't attempt. So, I am usually packing two boxes secure in deep,well buttoned pockets. Is there some dresscode or wilderness rule requiring merely one PSK? What about 3? Those who find some form of food a priority,real or not can simply build a aggressively thought out PSK and add more units for food,first aid etc.. A small tin for food items is still no Moveable feast. Yet for fun I just loaded a tin with tea, bullion cubes, food tablets, chocolate, a bit of jerked meat , dehydrated fruit and matches.
