Query: great basic info for eating well on the trail.....

I enjoyed this book very much, and after realizing that some of the images(suggesting one hold a piece of friut leather up to the sun to form a pretty,natural stained glass window)are meant to be more aesthetic than practical, I was able to glean some great advice and guidance. One note of caution: The item list for emergency backpacking food rations was good, provided you can employ six husky Sherpas to carry it all. All in all,a very good book for anyone interested in delving deeper into the art and science of eating well on the trail....
