I'm not sure about 502, but every other unit has outfitters permitted and guiding for the unlimiteds. It's not a highly booked hunt though. When it is booked it comes at a pretty high price tag, and most clients know the odds of success are still slim.
I believe the above mentioned outfitter must have been absaroka beartooth outfitters- Cameron Mayo. He must have revamped his website recently because there used to be pics of harvested Rams on there. The outfitting business is a really hard ticket to build a life upon. So many variables to juggle the average person would never hack it, so take some info off the internet with a grain of salt. I know ABO has alot of repeat clients.
I know alot of this because between myself and several of my closest friends we have guided for several of these outfitters. I only guided for one. The one who got the permit from Jack Jr himself. He has since passed the permit on to the outfitter who has it now.It was back in 2012 that I guided two sheep hunters, so more grains of salt there I guess. The two guys I guided were both wealthy, in there 50s, and had no interest in my plan for their best chance to find and harvest a ram. On a ten day booked hunt they both tapped out on day three.
It's just not a money maker for the outfitters like elk and deer hunts...but there willing to sell it if they can.
