I live on a large WMA in North Georgia, there are thousands of people on the Southern end of this WMA annually in and out of hunting season. There are 40 miles of bicycle and horse trails throuhout the area not to mention the hikers and casual visitors to the area. Deer adapt to the human presence and pretty much ignore it. When the first string is dropped when archery season begins and the first cap is busted during muzzle loader season, all bets are off.
When I was a kid in Northern Wisconsin, the guys cutting pulp wood, would wait until their working buddies left the woods, and then would get into their stands and as likely as not, drop a deer as soon as the noise was quieted. In short, scout all you want and don' t worry about it. Most deer never travel more than seven or eight hundred yards from where they are born during their entire life. If you are truly scouting and learn as much as possible from their movements, feeding and bedding areas you will be in good shape.
