Tree stands are not a bow hunting requirement.
Good concealment and scent control can make a stalk hunter just as successful, and I find it much more entertaining.
I don't have the patience to sit for long hours in one place.
I stalked within 35 yards of a big doe yesterday. She was bedded down to escape the hurricane force winds.
Just as I was standing up to draw my bow, I got busted by two more does (evidently stalking ME) who were 20 yards behind me. The wind was favorable, but so strong that I couldn't hear a thing, and I had no idea they were there.
