Few Oaks on my place are old enough to produce acorns. I think the multiple areas of dense cover along with plenty of watering holes and browse are what attracts the deer. I think it is the oases of wildlands in a sea of row crops that does it. Not just my place, but some of the surrounding ground as well. Over Hunting on some of the surrounding ground appears to push the deer into my place where they are not bothered (in designated places where we never go unless we are following a blood trail). Even our dogs are not allowed in these areas.
