I have jumped deer in clear cuts as wide as only about 100 yards and surrounded by a switchback. I have been close enough to smell them (about 5 feet) before they broke from their beds. If you see sign, or not, give it a try.
Another trick is a fawn distress call from the edge to see if anything stands up to see what the ruckus is about.
ETA: Just noticed this was in the archery section. This was specifically rifle hunting, although I guess you could try it with a partner in a driven game scenario.
