I've been pretty upset about the decline in that unit and the surrounding area as it was one of my favorite places to go. To me it's been a combination of "Loving it to Death" by many of us who like to hunt there - and the perfect storm of the other factors I mentioned before.
I'm going to stop hunting there for a few years and pray for the herd to recover. I'm sad about not hunting there, but I'm looking forward to learning new areas.
