"Travel Light, Eat Heavy Along the Appalachian Trail and Other Mystical Routes (Paperback)" Bill McCartney (Author)http://www.amazon.com/Travel-Light-Appal...4923&sr=8-1
This book has been out of print for several years, and I found it accidentally.
The deal with this book is that you "Cook" by the "Boil, Pour, Stir, Wait, and Eat" method, but you don't do any dehydrating.
All the foods are said to be available from grocery stores, making resupply pretty easy.
You can buy from Amazon.com for $17.76 plus shipping or you can buy from one of those alternate sources in "4 New from $14.95", plus shipping. The alternate New seller is Gray House Press, which is actually the author, Bill McCartney.
That is where I bought mine and it is on the way via USPS.
The Amazon.com site lets you read a dozen or so pages and look through much of the index. So, you can get an idea of if it is anything you would like to have.
