I remember a red stag guide in Scotland who had two clients 500 yards directly downwind of some magnificent animals. Normally, that’s a no-go. But he noticed the deer were feeding in a notch, and off to one side of the notch. Further, he knew that wind swirls in such places. Further still, knowing that animals don’t care for swirling winds, he predicted that they would keep moving in the direction they were headed until they got to steadier winds. Long story short—I’m not sure I understand this completely, but the guide sure did—he was able to hustle his clients directly upwind towards them and kill the largest. It was all about the “carry,” which is what Scotch highland hunters call the behavior of the wind.
