I have noticed for some time that bucks seem to share common antler characteristics by geographical location. I know a family that has a barn full of antlers from the same hill behind their house, all the mature bucks are 3 points. There are a couple with more points per side, but they all have a 3 point main frame.
The areas I concentrate on for the most part are all with in 20 miles of each other, however only a couple of spots seem to consistently produce 4x4 bucks. Some areas seem to have tall, narrow racks. Other areas a couple of creeks over produce wide racked deer.
None of the deer locally migrate more than a couple of miles. I am thinking that these deer may need to wander a little more and break up the gene pools? I am fondling the racks from both this year and last, and although different, they are strikingly similar. These two bucks could have been shot from the same treestand. Same ridge, within 30 yards of each other.

This photo does not show it well, but last years buck on the right has several inches of antler broken off. He seems to be a year younger than the other judging from skull size. No eyeguards on either deer, both mature animals.
Do any of you have like examples to share? I think it is very interesting.
