RE: Human Activiity on Hunting Grounds.
Actually the best thing to do is spend as much time possible day and night close enough to the deer so that they know you are there, far enough away that you don't spook them. Just like any other animal, they will start to slowly accept your presence and you will no longer be a threat to them.
However, for this to work plan on spending at least 5 days a week for oh, 6 months or so. Unfortunately I've never had the time to do this.
I remember seeing footage of Marty Stouffer (like him or not) go from being hundreds of yards from a band of Big Horn sheep to sitting among them and actually feeding them by hand. It only took him 8 months to do this.
