In my experience, most mature and even some immature bucks will stage just inside the woods until past legal shooting time. Ive killed two decent bucks by placing my stand about 40 yards from the edge of the field. Both of these bucks were shot about 5 minutes before the end of legal shooting time. They both approached and stood there apparantly waiting for the last bit of light to fade.
The heat of the rut can change this though. When the rut is in full swing just follow the does.
