I guess it really depends on your location, if you hunt semi urban areas like I do, it really doesnt matter. The deer are use to human sents and it really doesnt bother them as much as if you might be out were deer dont have much human contact. To this I would say, take along some cover sents, fox urine would be best, after you get through with your duties, cover the area with the sent and move on out and dont go back until opening morning.
