I've hiked through 27-2 a few times. It's desolate country. I spotted some sheep in there, on my way to ship lake. This unit will probably take some patience and mental toughness. PM me if you want any specific information. Good luck to you.
Stacy, I've hunted that unit a couple of times, most recently last year. I don't have a bighorn yet. I have a little personal experience on what not to do, so PM me if you would like my input on that .
I hunted 27-1 which is just north of your unit two years ago. Access is a problem because it is at least a 10 mile hike just to reach the unit. Wilderness area all the way. Horses would be important in getting in and out without losing your meat or trophy. There are some guys who have done it on foot but it is a tough hunt. Only one outfitter allowed to go in there. PM me and I can share what I do know.
From the books that I have read, there is a lot of importance in knowing every nook and cranny of your hunting territory as well as the animal that you are hunting. So scouting as much as possible, just walking the land, will give you a good idea of what's around the corner or what's on the other side of a hill. Which can be very beneficial.
