simply not "huntable" numbers. The state does not want them here and it's pretty much open season on them when anyone spots them. Because of this, they are kept in check near the s.e. corner of the state, and won't spread any further because they are "shoot on site" critters and that open country down there won't allow them to proliferate further into the state. You'll hear stories of a few around, but there aren't enough to plan a hunt for them.
