I suppose thinking about these things might sound a bit silly as fir cones are free....
Last night we were playing with it. We had only one cardboard box and a newspaper.
We had no matches or lighter, only the firesteel and some birch bark.
With the lid off the pot, we struggled getting a litre of water to the boil with it.
It was blowing hard and raining a bit - enough to damp our paper supply and make keeping it alive difficult.
If I can make this thing as No Idea proof as possible while Im playing with it at home,
It will pay me back 100 times over when I really need it and Im stuck in a ditch soaked through and too tired to think properly let alone get up and go looking for more pigging fuel and something else to get it to start when everything is soaked
Of course, Im not a pessimist, I just know how stupid I am.
