The BMA (Cascade, MT) where I hunt antelope is a ranch that holds a heard of approximately 400 (at least last year) ... maybe more. I do spot and stalk only. When I bowhunted last year, it seems that I was the only one around. Got closed to about 30 yards on a nice buck (~16" +) until the doe gave me away. Also, had full draw on a young buck (~10") at less than 15 yards but had to let it go ... I only have less than 15 minutes of daylight left and did not feel like looking for him in the dark if I didn't do my part.
There is also a neighboring rancher that is not part of a BMA that has quite a spread but he is hard to deal with and quite the cranky old man.
The BMA is a sign in/sign out deal and no need to call for advance reservations. The other BMAs (4 or 5 with a couple of mikes from each other) in the vicinity requires at least 24 hour notice and will have to sign in that day, which means you cannot go to your spot early.
If this is something you might be interested, let me know and I can get you more information and map if already available.
