Hi Leadshot, I'm guessing you mean the Muddy Mtn. HMA that's north of Medicine Bow. I've hunted there before a few times for deer (including last year) and unless the snow or mud is bad, it's easy to access and there are lots of antelope. The area is built to hunt-lots of folds and hills-easier than many of the basin areas where it's so open. Plan on caring for the meat yourself, the only close processor is in Medicine Bow and they really suck. Good luck, that's a great part of the world.
