RE: Wind Direction?
If I am facing the direction I " think" a buck may come I personally never like to have the wind in my face. I don' t like a setup that relies on a buck moving with the wind to his back. I would much rather have a cross wind, or even better yet a wind quartering towards his direction, that still keeps my scent away from the primary trail / trails I am hunting. A much more riskier setup, but a setup much more likely IMO to achieve the results I am looking for.
Many of my deer were a 45 deg shift in wind away from busting me.
