Murdy, the success % looks pretty good because most of the deer are taken on private land. Yes, there is some public (BLM & State) land, but by and large it's over-run with hunters on the opening. Deer are pushed onto private land, and that's where they tend to stay. Unless you get permission to hunt one of these ranches ahead of time (call G&F for co-operating ranches) I wouldn't waste my time. I ran into some hunters from Minnesota last year at the Casper G&F office looking for a place to hunt, they ended-up going home without being able to get even an opportunity at a deer.
