A lot of the posts say what need to be said. Its extremely hard to pattern a mature buck. Hunting does on mountains is tough at times too because so many things affect which area they use....from food, water, scent, wind, temp, pressure, moon and etc.
However I guarantee you that both the buck and doe are creatures of habit and if you should put the time in you can figure out how many different paths they take to get to a few different destinations although knowing which one they will be on depends on all the variables I mentioned before.I understand that is easier said than done but I promise it can be done if you dont have to work for a living like most of us. Good luck.
