The bucks are there you just aren't seeing them. It sounds like Does are using this area primarily however treeclimber was right, there should be plenty of bucks around during the rut (Late November).

I would not be in a hurry to put in a food plot if there is other food sources available. Size would depend on how much land you can afford to provide if you decide to put one in.

Have you seen any bucks at all this year. Perhaps the bucks primarly nocturnal. Game Cam might answer that question. You might be surprised.

GO PACK!
