A wise old buck or a boss doe has another sense of survivability that most hunters aren't aware of --- Which is a form of mental telepathy that a deer can sense, when a nearby hunter starts to think about that deer that he sees and wants to harvest. It's like the same feeling that some people can sense, when someone is staring at them behind their back and they turn around and find someone is/was staring at them.

I ask a question to a couple of mental telepathics on a radio talk show many years ago...when I called in and asked them how can I prevent a deer from sensing my presence through mental telepathy? They answered that I would have to "think about swirling colors in my mind", when I'm taking a gander at the nearby deer.

Say you're after a trophy buck on your property --- Best bet is to limit your deer scouting drastically, or better yet...none at all. Once you invade his territory, and he sees or smells you...he'll be aware of your traverses and may possibly want to avoid your property in the coming future.
