I was talking with a river guide in West Virginia, around the New River Gorge, and he told me that in the late 1970s or early 80s, the over hunting had brought the average weight of the whitetails way down, so officials brought in Mulie does and let them loose to mingle with the whitetails. After only a few years, the average weights of harvested deer in the area were way up. Now he might have been putting me on, but he really seemed ernest. I might need to go check out what I can find online.
