Horses, Fishes, and Rocky Trails is a play on words from what became our "bible" for this trip.  The real title is Horses, Hitches, and Rocky Trails by Joe Back.  It is the ultimate book on horse packing.  The writing and illustrations are informative and entertaining.  Being experienced hikers and campers we used our own low impact style of camping.   However, when it comes to the "ins and outs" of getting a pack train ready to cover some distance, THIS IS THE BOOK!!!!
