Tough call. I like staying on the trail when possible but have waited four hours on questionable morning shots. Hate the tv shows that always back out till morning without even following the trail for 100 yards. They just want daylight to film the recovery. In coyote infested country stay on the trail. What is the difference between you jumping the deer or a pack of coyotes doing it? Coyotes don't wait till the deer is dead to get after it.
