Find the nastiest, heaviest cover around the area even if you have to wade water that would be belly deep on a deer to get there and that's probably where the biggest bucks will be found. We have places like that up in Michigan that they will wade in until they find a high spot to lay on and there is absolutely no way to approach them without them knowing it. You also need to remember that a big buck will not normally follow the trail that does and smaller bucks are using unless it;s during the rut and he;s out cruising for does.
