Tracking a person for many miles through wilderness and urban terrain is an art still practiced daily by some officers of the U.S. Border Patrol. Jack Kearney spent twenty-one years honing his skill of "Mantracking" by catching illegal entrants into the United States, finding lost persons in search and rescue operations, and assisting law enforcement agencies in criminal investigations from arson to murder. In addition, he spent many years teaching the art of tracking and devising the exercises listed in this book with which interested persons can self-teach themselves without needing the guidance of an expert tracker. Developing a proficiency in tracking skills can be an invaluable lifesaver for military, law enforcement, and search and rescue personnel. Although this book is principally about tracking people, it has been widely acclaimed by many famous and respected big game hunters. In one of the glowing reviews the book received, former Executive Editor of "Guns Ammo Magazine", Elmer Keith, declared, "Every hunter should have this book and study it." Bill Jordan's book, Mostly Huntin' devotes more than a page to extolling Mr. Kearney's skill and the virtues of his book and recommends its purchase "without reservation".
