Food source, hunting pressure, time of year (moon, rut, etc) weather conditions (rain, wind, fronts etc.) So many variables. It can be done, but I know of no one that can do it on a regular basis in the same area.
But just like any thing else once they get bumped or know you were there in their safe/comfort zone, or their travel routes they will change.
I try and stay on the fringes of the thicker bedding areas.
Many deer including mature deer will be in open big woods usally a third of the way below the ridge top in a blow down overlooking the bottoms.
But if you know they are in the thickets, going in after them may be only a one shot chance.
