Go back and keep looking for that bull. Last year a friend's wife arrowed one, the tracked it a LONG ways but thought it may not be hit bad (her draw weight is marginal, thought it might have been shallow).
The went back each day for 3 days, on the 3rd day they stopped for lunch and noticed some birds over the ridge. They climbed over and found 3 black bears fighting over her elk.
The meat was bad of course, but at least they salvaged the rack.
