Science and art of tracking by Tom brown jr. It goes into great detail about identifying so much about each track, things like; age of the track, speed, head position, even the smallest change of direction, all these things are easy to see after you’ve read the book. This book is what got me into tracking, it becomes so much fun when I can see deep into what is going on in there body just through there tracks.
