A crucial part in Tracking is played by observation of every detail which happens to be “out of order” in Nature. In fact, the gait of a person walking in a forest, for example, not only determines his presence in it, but it does also alterate the natural state of that particular kind of environment. What you may notice is sistematically coeherent with Tracking. There are disturbances, primarily on the ground, and then again, possibly, on trees or, onward, on the bush which can border that forest.
You pretty much come in contact with every single detail which is “out-of-order”. But it isn’t so simple to detect them.
As “practice makes perfect“, experience and costant, frantic training are essential when it comes to Tracking.
In “Training in Tracking” by Gilcraft (that you can easily download HERE, the Author highly recommends the practice of Kim’s Game in order to enhance not only your observation, but also your abilities in Tracking.
Worlwide Kim’s Game has been very popular among Scouts: beyond that, you will find in it an utter aid to your personal training development and accretion of your natural awareness.
