Last time I was there, quite a few years ago, my luck finding anyone good in Rawlins was bad, but I found a good meat processor in Encampment about 40 miles South of Rawlins. I used them & they did a great job & fast too. I do not recall the name of the business, but a call to a motel in that area would get their names. There was also a Taxidermist there too, he would know. Hope this helps you out !! ???
Best of Luck & Good Hunting!
