4 acres, that's a very small area and they should be at range if you hunt it right.
Park or sit somewhere away from where you normally sit and see if you can observe what goes on out there without the deer knowing you are there. Just use your instinct and guess which way you think they go to reach your hunting stand. Scouting and observing deer from far off will give you precise information so you can locate yourself exactly where they will be at range within that 4 acre.Always consider the wind and not even go out when the wind is not in your favor.
