Congrats on the tag but are you sure it's a OIL? All I know about that unit is that some of the best area is private and the landowner charges a fairly high fee for access. But there's also enough public land that you can get your sheep without having to pay for the private access.
Good luck. I'm sure you'll get plenty of help. Let me know if you want to contact the biologist for that area. I have a phone number and email address, he was very helpful last year with my sheep hunt.
