Hunting in NW ND a dozen or so years ago. We stalked a large whitetail buck as it was pushing a group of 4-5 does. He wound up down in a basin where a sizeable mulie buck had gathered a harem of 6-8 does. The whitetail ran right past the mulie which was larger in both physical and rack size and started scent checking the mulie does. The mulie just hung back and watched him work his harem. I don’t know what would’ve ultimately happened as the whitetail died of a sudden case of lead poisoning.
