Chris, the "instructor" is someone who is "well known" in this field. With a little searching I found the passage that I was remembering. He claims that the "advanced students" did not search in the right places for their materials. I found the passage in "Tom Brown's Field Guide to Wilderness Survival." It was under Fire Making Techniques/The Bow Drill/Wood Selection. <br><br>He definately has his detractors as well as his groupies. I have read some of his writings and those of others discussing him, but I have never met him personally so I can't comment in a reasonable manner.<br><br>I don't believe everything I read. I never have, but I give it the weight that I think it deserves. Sometimes I am more lenient than other times. I keep my mind as open as possible but in this case I tend to agree with you.
