I say bitter cold and it was for Central Texas ( 26 with a 20mph North wind ) I'm not sure what the wind chill was but it was cold , so there I sit in a tree along the edge of the river an hour before sun rise. Did I say it was cold well it was to me but all my wool kept me from shaking out of my tree. The deer started moving right as the sun was coming up , had a good 10pt working several doe around back and forth for an hour. He would offer me several shots and I drew on him a few times but held off cause it was still early and our rut is on. I saw the 10pt look down toward the river then all his hair stood up and he layed his ears back , but only for a few seconds. I could not see what he was looking at but he could then as fast as he bowed-up he turned and looked like you just whipped a puppy and started sneaking the other way. When I looked back I saw why a big ol body with a wide rack was heading my way and that 10pt wanted nothing to do with him.......
