If you hunt deer on a pattern and continuously are spreading your scent around THEIR living room,they will change their pattern.Might be only 50 yards and maybe only a few minutes difference but they will change it.
This kind of thing might not be a big issue for a gun hunter that only hunts during the rut phases but to a bowhunter that is trying to pattern a deer on a travel corridor,he definitely doesn't want to kill a couple deer in an area and lay on the ground and gut a deer.ESPECIALLY if you are trying to get on a big mature buck outside of the rut.If hunting a mature buck,I don't even want to kill anything in the area due to spreading my scent around.I will pass in the core areas of a mature buck.
