Have you tried to get there early and see where the bucks are coming from. If they are crossing you property to get to the field I'd get between the bedding aera and where they enter the field from. This sounds like a chore that may pay off opening day if you play your cards right.

It's a little late to plant now. Your could try to plant some winter crops to entice the deer to feed on your property. Play it safe and check the law book though. I'm not sure the legality of food plots in PA.
