Just when I think I know how to get close to one of them they usually don't do the same thing or I never see them. So I voted for I hunt for immature deer! Seriously, I just go out there and hunt and try to find a big deer by moving around and hunting different areas. I hunt very high pressured public land and I don't see big deer in the same spot in consecutive years. One of these days when I have my own land to hunt and have all the time I need to be proficient I will try to do what I can to learn everything about them. However this area I hunt is great land and I do see big deer each year I just have not been able to get a good shot on one yet. Did I mention it is thick!
