for the most part you are correct on the 120 8-pointers, but there are deer bigger than that in williamson county. not a lot of them, but if they get the time to grow they can definitely get to 140 if not better on rare occasions. age is the limiting factor in most of the eastern hill country, if you can get around that you will find some nice deer.

Someone strums a mandolin, soft gulf breezes blow
