I placed my ground blind out about a month ago and the deer are just getting used to seeing it. It may take a while for them to get used to it. Also even though threes shadow guard in the blind, it doesnt help of you have all windows open I open only two windows where I expect the deer to be comming in from. To my north and to my west. West being my main window for ops. I am set in a thick patch of pines with a corn field no more that 20 yards to the east of me (Behind me), and to the north all I see is pines, to the west I over look a swail that is heavilly used. I keep the south window and the east windows closed because if a deer was going to come in from the south id be able to see them from my west window and to the east theyd have to come in from the north, so I keep the east window closed. Makes it a little darker in there, and when it starts gettig a bit darker i open the windows just enough to let a little bit of light in to see my sights.
