You guys are Full of It. All the deer do migrate across the lake to sunny Manson, get eaten by the Methow Valley wolves and are never seen again.
That's way we call it the Deerless Entiat. There really is no reason for anyone to hunt the GMUs south of Lake Chelan (Entiat, Slide Ridge, Chiwawa, Clark, Swakane, Mission, Alpine); wolves ate them.
