deer anywhere can get accustomed to humans making noise. My property borders two other properties where the neighbors are always making noise I use mine for hunting only, the neighbors live there. I for the longest time thought they would be on alert or not coming in. but after spending some time in the blind they dont even twitch when the neighbors are making noise. Its what they have gotten used to. Now in the blind if I make some noise they white flag me and are gone. Because its not normal.
