This time of year bucks are breaking out of their bachelor groups and going into almost a hiding mode. They're really just resting up and getting ready for the rut. They are cruising different routes than they do in the summer. Also using different bedding areas. They're there, trust me. They just are starting to get their mind right to chase does and are also being recluses. This is a normal pattern. Best advice I can give is don't give up or lose hope. Also try hunting closer to bedding areas, this time of year. Better luck maybe catching a buck leaving or returning.
