Its kind of embarrassing, but I didn't used to carry a method of starting a fire on a regular basis until I saw the movie Cast Away, and that got me to thinking how tough it would be to start a file without any extra gear, how easy it would be to carry a tiny Boy Scout Hotspark ferro rod.

In my mind its kind of silly not to carry at least something since making fire with natural materials is so tough for most of us.

BTW, here I'm talking about getting the "spark", not so much about carrying material that lights easily ... which would be a great idea if outdoors (camping, backpacking, ...).
