Don't forget about char cloth replacements...
Hope I'm not jumping too far off topic, but I want to share something I learned last winter, maybe you all new this, but it was new to me.
I was out trekking in the snow and of course it started to rain, stopped to make a fire and cook lunch and realized that the new batch of char cloth never made it into my haversack.
Sitting there cold, wet and hungry I looked up at a big growth on the side of a birch tree and remembered reading about "Tinder Fungus". I smacked it off the tree with my belt axe and thought why not try...it was like a hard ugly bowl filled with an orange sponge...before it got too wet in the rain I hit the flint and steel a few times and actually got an ember to take...of course it went right out cuz I was not prepared to actually start a fire (no wood collected yet)...remember the be prepared part????
Anyway, long story short, I got prepared and managed to start the fire with my new "orange sponge" and finally got to eat my lunch.
I took what was left home and put it by the wood stove, it works even better dried in this manner.
