The Shadowwolves are a Native American Tracking Unit, operating on the Mexican Border and beyond. http://www.smithsonianmag.com/people-places/wolves.html
They have a tradition of being stealthy trackers, hence the name. One of the founders was so stealthy that he could move into a group of people sleeping in the desert and remove items from their camp. Just a small point, but these people were armed, dangerous and very wylie.
I carry that tradition on. During our courses I take a select few, and they practice some of the skills required to shadow very close to people. Its a real skill, and takes time,dedication, determination and concentration.
One of the things that I reflect upon, is why I teach tracking to people, and I suppose this letter explains why in the words" Please take your knowledge and make good use of it. Your efforts are appreciated by all"
It was written by a senior Shadowwolf, the letter is short and very meaningfull.
Because the Shadowwolves are a covert organisation, I have blanked out the officers name.
