one more thing: its obviously a good idea to keep firestarting things as dry as possible no matter how effective they are in foul weather.

Leighman: I would say that if your PSK is weatherproof, that you should def. keep all firestarting tinder within it as a general rule. I keep my petrol-coated cotton balls in a plastic film canister, and the entire PSK inside a water-tight sandwich-sized Tupperware.
