RE: Nocturnal buck??
KT, if he's nearly that old, he didn't get that old by being stupid!
As I said, you'd probably have to find his bedding area and hunt early and late to catch him.
Older bucks can sometimes be almost un-huntable!
On the last place I hunted, one hunter had a stand on a good creek bottom, and he never even knew this buck was there! The buck had a bed right near the logging road, about 30 yards from where this hunter went into the woods! The buck would probably just lay there and watch the hunter go to his stand!
I saw this buck twice. Once one afternoon while bow hunting, and then again the very next morning! Both times he came within 10 yards of the logging road, stood a while, and then he'd turn and go back into the thicket! Had I been gun hunting I'd have had a shot, but he was much too far for a bow shot.
I relate this to make the point, some big, older bucks are nearly un-huntable! But theres always a chance they will make a mistake! Usually very early or very late! Good luck!
