It is a tough way to hunt with a short range weapon.One of the problems,especially in the mountains is wind direction.Not a problem if the animal is way ahead but you are having to stay within sight of the track regardless of wind direction.It is easy to say just make a wide loop when wind direction is wrong and come back to the track but in mountainous terrain,such detours can wear you out long before you hit the end of a long track.Animals also tend to watch their back trails and when bedding,they often make a loop and lay watching their back trail,with the wind at their back.Most animals,mature ones for sure,are very aware they are leaving tracks.
