"Animal Tracking Basics" by Jon Young and Tiffany Morgan, 2007, about 280 pages. My impression is the best use for this book is as a summer camp workbook for kids, coupled with a standard field guide like Peterson's Animal Tracks. Ms. Morgan writes well and I enjoyed the what she had to share. Mr. Young, as the first student of Tom Brown, Jr., wrote about interesting exercises in "air sculpting" to aid story-telling about animals, animal movement emulation, journaling, and mapping. For somewhat older folks, Mr. Young's writing could form the basis for discussions of appropriate human-animal interaction, the limits of knowledge versus speculation, various logical fallacies, defining and relying on intuition to understand nature, and science versus belief.
