The wife bought me one of those primitive fire kits that they sell online. Using the raw piece of flint, steel, char cloth and cotton wool that came in the kit, I managed to get a fire going. It wasn't easy and it took several tries before I got it right and actually acheived flame. I would imagine that the more this system was used, that we would eventually get better at using it, that or we'd get smart and do what our ancestors did. That'd be, carry a smoldering coal with us as we traveled. ; - )
