"The first track is the end of a string. At the far end, a being is moving; a mystery, dropping a hint about itself every so many feet, telling you more about itself until you can almost see it, even before you come to it. The mystery reveals itself slowly, track by track, giving its genealogy early to coax you in. Further on, it will tell you the intimate details of its life and work, until you know the maker of the track like a lifelong friend."
-- Tom Brown Jr, from The Tracker
