I usually just walk in to my "spot" and sit down with my back to a tree. There are a few brush piles and low tree limbs that kind of screen us. So long as you don't make any noise or sudden moves, deer are pretty oblivious, particularly during the rut, which generally coincides w/ opening weekend of the Firearm Deer season in Nebraska.
I have had deer walk right by me and the kids ......I have been taking 2 or 3 of my kids and nephews and nieces for about 10 years now. I've shot deer as close as 15 feet, and as far as 460 yards...... none were even looking at me when they got whacked.
