Burns/Crane Oregon has multiple different sage rat guide services and is one of the better areas for good shooting. Unfortunately, like many things, it has become a business so the vast majority of land gets tired up and rented by the different guides. If you're looking for somewhere to go so you can do your own thing, best of luck to you because unless you already have somewhere to shoot, it's tough to find places and the ones you may find, probably won't have that great of shooting.
I've shot sage rats in Crane with No Off Season, a few times. Tim provides a good service and the sage rat shooting is generally pretty good, although, it seems like there are a few less rats every year. I haven't been for a couple years so I'm not sure what it's like now.
