For sure, deer pattern hunters alot better than hunters pattern deer. I will never forget something that happend to me years ago. It was when I first began bowhunting, and I was hunting the same stand over and over. When November came around, I hunted in it everyday for about 2 weeks or so. One day I saw a big 5x4 slipping through the brush. He stuck his head out and looked directly at me in the tree. He was far enough away, that he did not notice that I also saw him looking at me. He slowly turned around and went the other direction. He did not smell me. I had the wind. Nor did he smell where I came in at, since he was nowhere near my entry path. He also did not see any movement since he was far enough away that I did not even begin to get ready for a shot. I have never seen another deer do anything like it, but I am 100% convinced that this deer knew I was hunting there, and decided to check before he moved through the area. More than likely, he had spotted me in the stand on a previous day, and I never saw him.
It's hard to do, but I think it helps to only hunt a stand once every week at the very most. Too much more than that, and the deer will surely figure you out.
If you think about it....people are much easier to pattern than deer. Most of us enter and leave the woods at about the same times every day. Plus, many of us hunt the same stands over and over. It does not take them long to figure this out.
