I once managed enough hot ember by using a homemade bow drill to light a tinder bundle, but that's about as far as that got lol. So many other ways to be prepared to go about building fire it's really not worth the effort unless it's to test your own skills or amuse a crowd.
Then again at one point this winter my fingers got so cold I couldn't use them propperly to get a lighter lit much less a fire started. That's when a fresh set of legs to get you back to camp quickly where the coals are already stoked are your best friend.:yes:
