I carrry two kits . Past threads with valuable input from our M.D.'s;Tustbox and Beachdoc have helped define the limits and realities of such kits. Nobody is going to set up a triage station out of a Altoids tin. What we can do and expect is to keep minor wounds such as foot blisters from turning into debilitating infections, manage pain and perhaps start a antibiotic regimen. Remember that a PSK is a last ditch assembly of the basics. There is no rule stating you can only carry one. Personally with two matching tins in my pockets I can follow a compass heading without vearing to the wieghted side <img src="images/graemlins/grin.gif" alt="" />
