I always hear that stands can be overhunted and I have done this in the past....successfully. They say even though you don't see any deer from that particular stand you are leaving behind scent which can be detrimental to your hunting. This is true but I have hunted stands consistently (3-5 days at a time) and I have been successful. The buck I got last year only came through every few days, very much like your situation. So I hunted that stand every evening for a few days. If I would have kept changing stands than there is a good chance I would not have gotten him.

Its a guessing game...it really is. You think you may be doing yourself a favor by moving around a lot but that day you do move may be the day the big boy comes through.
