Hunt during the week, be in your stand early, and avoid all noise to catch one at your feeder just before he beds down for the day. Any unnecessary noise will tip him off that he should pass up a bedtime snack and hit your feeder after dark. They don't get old being stupid and the rut that was once in your favor is now in the books. And since they now know full well everyone is after them, stealth is essential.
Otherwise, just enjoy the mud with your ATV and taking shots at hungry doe and lesser bucks.
