Deer do wise up as season progresses. One of our properties has about 50 acres of ravines, sumac, wild plum, greenbriars, oak brush and downed trees from a fire that came roaring through the place seven years ago. i never go there because it's impossible to get through the place without a machete.
When the guns start to crack the deer from about 2,000 acres of the neighbors property head into that thicket and come out only at night.
