The best answer to this riddle is to be found in late January and February. Especially if there is snow cover, track them in the snow till you start jumping deer. Look for specific tracks that would help you identify a large buck and follow them. You will find his home and it wont matter because by then most seasons are over. Even if there isn't any snow cover, the trails will tell the story. It will be more difficult without snow but the sign will remain. Start at the food source and back track. I will say that just because you see a monster buck on your hunting property during the rut does not mean he will be there pre or post rut. Some deer will travel great distances when the urge makes them crazy, but will live in a very limited area when they are not all consumed by the ultimate urge.
