Jared welcome BGH! This year has been one of the worst I have ever seen when it comes to the elk.
I only had a cow tag this rifle season and never even seen an elk. I walked 14 miles round trip into one of my hidden holes, and tried many other holes I have in out of the way spots, and found very few tracks. I have been up there since the beginning of archery season and it is truely depressing the way things have been with the elk this year. ,)
If you are willing to work and walk a long ways I would concentrate on Star Mesa, Flat Iron Canyon, and the Badlands.
As a Taxidermist I look at hundreds of Whitetail Bucks every year. I know that I have seen many different ways people judge the size of racks on live deer. I think for the most part they all are pretty close. I'm going to give you some measurements that I have noticed being right on in just about every deer. We have used it in the last couple years and have only been off by about 5-6 inches. We do study the deer while bowhunting so we get a little more time to look at them....
