The best ground blind is not artificial. Find a place where (1) you sit in the shadows, (2) brush clutter breaks up the view of your lower body, (3) brush or trees break up your outline behind you, and (4) avoid being silouetted. Then,when you sit there waiting for a deer to show up, move little and when you do move, move slowly. Wear something that covers your shiny skin -- a face net, gloves. On any given day's hunt choose to sit downwind from where you expect to see the deer. There is freedom in this approach to hunting, and that is good. It makes hunting funner. It makes you engage your brain, and the most powerful hunting weapon is your brain -- figuring out what the prey animal is going to do and place yourself where you are in a position to shoot that prey animal.
