I have while bowhunting. I had a spot where I scored several times over the years usually when the wind was right and on the first or second night in the stand. On years when I failed to score I kept going back and the deer sightings would dramatically fall off after the third night. I was always careful on scent control but just going to and leaving the stand takes its toll. No telling how many deer either see you or hear you when you leave the stand at dark. It doesn't take long before they know you are there and go around you. Now I never use the same stand more than 2 times in a row and then don't go back for at least 3 or 4 days. My success has gone up when I place several stands in an area and alternate every night and try to use the wind in the selection.
