Full disclosure here: I am a personal friend and associate of Don Martin of Arizona Wildlife Outfitters. We have hunted and fished together for years and we are both Chief Hunter Education Instructors for the AZGFD.
I do not often recommend outfitters and guides on MM, I have done it a few times over the many years I have visited here, but I don't make a habit of it. That said, I have been applying since my 20's for DBS tag in AZ and a few other states. I have never drawn, and 60 is my next significant milestone birthday. When I do, Don will be in camp with me.
If your friend wants to kill the sheep he explains he is after, the one that fills his mind's-eye when he dreams of Nelson Desert Sheep in AZ GMU 15D, he could do no better than Don Martin. He'll get all 31 days if needed, every effort from Don and his staff, he'll eat good and have a comfortable place to lay his head every night, and...he will be cautioned before squeezing the trigger on just what he has in his crosshairs before sending a bullet downrange at the sheep of his dreams.
Good luck to a another guy who "got my tag!"
I look forward to seeing his beautiful sheep's photos.
