I agree with bow huntert, hunting anything on this property will have an adverse effect on mature bucks. The neighbor riding horses or walking their dogs, as long as they don't chase deer, will probably not effect the deer, although too much human activity may deter mature bucks from using the area. Whitetails have adapted to being around people so some human workings will not effect them. If I have control of the activity I usually curtail as much exposure when the hunting season gets close.
