I really don't worry much about a camo pattern in rifle season anymore due to the blaze orange you will be wearing anyway. Speaking of which you only need to wear a hat OR a vest there, both are not neccessary and unlike Colorado you are allowed to wear camo blaze orange as opposed to solid.
I pretty much buy whatever camo I can get on sale. The sale stuff I have gotten though was a bunch of Mossy Oak brush pattern. It's light shades af tan and grassy look seems to blend really well in the dry areas. Of course all my hunting up there has been for antelope and the terrain is slightly different but I think it would still work well.
i've hunted region m, before on the general license and limited quota tags.
since all you are required to wear for orange in wyoming, is a ball cap... and it can be camo-orange, i wear the cabelas wootimate pullover in outfitter high plains camo... and at a few hundred yards, the texture of the wool, and the tones of the camo really make you difficult to pick out even to the naked human eye. and the goats and deer just don't see like we do.
i hunted unit 36 on a general license last year. i saw 15 deer. one small 4x4, some spikes and does. 3 wolves and 3 elk. i also found a whitetail shed in the scrub.
since the wolves moved into the birdseye pass area, i would stay away from that like the plague. you can go further east in those mountains, and i greatly reccomend it.i wish we'd gone about 15 miles further east than we hunted, but it's super hard to walk that far, and the roads that run through there are not traversable so much.
all the outfitter camo is good stuff for wyoming and the high plains region.
Bring them in on a string. I love this term, if you want to be successful on calling in Elk, try not to just sound like the other caller. We all laugh at each other when we are practicing Elk calling at home or while camping. When I first started calling in Elk, I had no idea what i was doing and it's funny how many I could call in. The biggest Bull that I have called in to date was actually my first. I was making cow calls and screwing it up big time. But it's obvious I didn't screw up...
