Thanks for the insight Tracker. This is a very interesting thread.<br><br>The passage in his book did not go into any detail over his whereabouts during the exercise. He simply said a group of his advanced students were unable to successfully make fire with a bow and drill set for a week, and that they went without fire. Maybe the wording made certain impressions on me. I read this book 15 years ago and in whole it certainly make an impression on me,however it has been years since I have picked it up and looked at it.<br><br>Overall I really like the book, and I appreciate his being able to go into the wilderness "naked and survive" approach. I based my little essentials bag on his "survival belt pack" in the last chapter. <br><br>Chris, the reason for my original post was to agree with you that a redundancy in fire making methods is needed. It is certainly that important to me.
