I was afraid it was a poorly constructed purely product marketing and involving only anecdotal information. But it's a nice surprise, far from Bear Grylls gives the spectacular chowing foulest things that the other one for the camera, or one that has left a range of derivatives, survival gear / hike to Yet the exorbitant price of lower quality
To summarize I liked this book (to clarify that I practice hiking and horseback but this is my first book on this subject, like many other person is written, there is no other book most complete, the "survivors" do lapprécieront experienced can not be much)
