trailing

The question that a lot of people always want to ask but don't when it comes to trailing: Is this real? Can a you or I really learn to follow a trail, track by track, without the aid of sand or snow or mud? It is common in myths, books, and movies to see incredible feats of tracking and several hyped up and popularized trackers make wild claims of skill with little to no verification, so it leaves a question, is the art of trailing real or just something humans wish they could do? Do you have to be a wilderness god or raised by indigenous people to really be able to trail?
