Query: Bushcraft

I found this book over 15 years ago as a highschool student, and felt then that it was the best book on outdoor skills I had ever read. Now, as a Marine teaching jungle survival in Okinawa, I use it as my primary reference, (and guard it with my life). This book is is well written and the pictures and diagrams are superb. I still rate it as the best book on outdoor survival I've ever read.
