It is an excellent book, I think probably the best survival book. It is not just an encyclopedia of survival techniques, it walks through the prevention, preparation dealing with the actual situation. Out of all of the survival books I have and have read, it is the single best, in my humble opinion.
There are still copies available, but the prices is going up and they are getting a little bit harder to find on Amazon. I had not seen it on that web sight. Thanks.
