My stand is 16 feet high. Nothing surrounding me. I take pride that deer do not bust me. Even though I am in the open I slowly lean on the tree to help me stay motionless. Deer are color blind. My orange pants seem flourescent but the deer never look my way. Nothing covering my face.
I have seen many deer coming from all directions.

Stay still and move your head and body like an owl. Keep your foot movement to a minimum. And I rarely sit, mostly standing.
