Heard a story about a bow hunt this week that a guy shot a buck that headed towards water, followed great blood trail right to a lake and thinks the deer swam out and sank, to never find it. He also said that at the same time he was looking for the deer a doe with an arrow in her swam into the lake and sank right in front of him. Sounds funny, would like to call his bluff. From the shows I've seen they usually find the dead deer floating in the lake, yes or no.
