I do not live close. I have hunted mule deer two years, mainly scouting for elk and moose in this unit. From what I gather from talking with other hunters while in the unit, the deer numbers are way down. Being a flat lander, I was fairly impressed with the deer numbers, but would rate the buck quality low. I am still going to purchase a deer tag if left overs are available. I would say there are low end P&Y bucks there if you hunt hard. Just my experience.
The biggest thing I have taken away from hunting the Big Horns is the number of people. They will be crawling every where. I am still applying though because of my time and money spent scouting the unit.
