I agree, if someone were to purchase only one book, this would be my choice. There is a lot of great info out there and this book does a fairly good job of putting out a good basic knowledge of survival. Of course, situation dictates and some times even the most info packed book can come up short.I like the SAS handbooks myself. I believe you can download those online as well. When it comes to my survival info though I prefer to have a hard copy.
I own this book and highly recommend it. It brings to light another aspect of survival geared more towards the day hiker or casual hiker who is not prepared for a long haul in the woods. Book makes great points in planning and prep for the first 72 hours after becomming lost or hurt in the woods. Definely a nice change from the usual survival info.I have looked through the book 98.6 degrees: the art of keeping your a$$ alive. I haven't read the whole thing but it seems interesting and doesn't just reformat the same material that is in SAS handbook.
Cody Lundin's 2nd book "When All Hell Breaks Loose" is a good read on this subject. Here's a link to a review of this book.I don't currently have any survival books. Yet, the subject of survival as it relates to disaster planning is very interesting to me. If you were to prioritize a book that deals that topic, what would it be?
