The wilderness is rough, and you’ve got to be prepared for any challenge it might throw your way. Like, say, starting a fire when you’re stuck without matches, flint or your trusty Bic. So we asked Thomas Coyne of the Survival Training School of California to demonstrate how to build a fire from scratch. All you need are sticks, a stone, and a bit of shoelace or rope. (You know, the same stuff Rihanna asked you to bring on your first date.)
