I have a cabin and some land north of Jordan, bordering the CMR in the Missouri Breaks. Pretty good muley hunting (a lot of bucks in the 120-160 range, occassionally you'll see a real nice one.) Also, pretty good antelope hunting, although it's one of the more popular antelope districts in the state, so it gets a lot of pressure. It's really known for it's elk hunting - some very nice bulls, but not a huge herd. There's a limited number of rifle tags for bulls (I've never drawn one in over ten years of trying), but the archery tags are unlimited.
If you draw a tag, let me know. We can compare notes, etc.
