It has been a few years since I have hunted the Sundance area. I hunted two private ranches. You will see a good mix of both whitetail and muley in that area. should have a good deer population, but you will have your share of hunters also on public land.
My longest shot in that area was about 125 yards, which is close range for most of Wyoming. this was due to the amount of forest land Vs. open range land. You will be lucky to see a good trophy head on public land, but it does happen on occasion. If you see a decent 4 point, think about taking him, unless you are dead set on a large 4 point or better. when I say 4 point, I am talking about western count, not both sides.
