I have seen that in bookstores and leafed through it. Lot's of interesting information and ideas. I tend to rely only on what I have actually seen or done but it would be a great resource for ideas to try out, specific to the places you hike. It is rather heavy to carry, but would be good reading in winter camping when the nights are long. If I was to carry a reference with me for survival it would be a aide memoire that I wrote myself and made sketches in with room for notes. Not that I know anything, but I think by transcribing more specific material ahead of time you would be more likely to be familiar with it and able to find it useful. It is rather like studying for an exam, isn't it. It is really better to do you homework yourself and attend all the labs throughout the year rather than relying too much on cheat notes. <img src="/forums/images/graemlins/smile.gif" alt="" />
