ASAR's own member, Rob Speiden, has published a book called Foundations for Awareness, Signcutting and Tracking. It is a must read!
Are you interested in tracking skills? If you have spent any time outside, you have come across tracks or sign left by animals and people. If you have ever wondered how to interpret, and even follow, human tracks or sign, this book is for you. This second edition book imparts knowledge necessary to answer the questions “What happened here?” and “Who made that track?” This is an essential book for encouraging and developing your awareness of the outdoors. It is a great aid for property owners, hunters, naturalists, search and rescue teams, military instructors and law enforcement agencies.
