NOW is the time to cut a trail in to his bedding area. Try to make it as cross-breezed as you can based on the prevailing winds. Then, hunt there ONLY when the wind is in your favor and don't overhunt it. Pick out the trees you want to use NOW and do your major pruning to cut shooting lanes. By doing all of this now, and then avoiding the area as much as possible, he will feel safe once again by the time the season opens. As soon as the wind favors you, go after him. The rut sometimes takes bucks out of their usual areas. Also, try to pattern him from a safe distance.
