AT,
I used to live in Sidney, Nebraska and I hunted turkey's in that area for the last two seasons. Success can be found in the Pine Ridge area but be prepared for competition and you need to be willing to hike in deeper than the average guy. Even though it burned last year, there are still lots of turkeys up there. Look to the Five Points area north of Harrison and some of the walk-in areas around there along the creek drainages. The Gilbert-Baker WMA is another good place that didn't see the fires like the rest of the ridge did. Also, it never hurts to knock on doors up there as friendly ranchers abound and are usually more than happy to let you shoot a few turkeys. Use your calls sparingly later in the season as a lot of those birds have had lots of run ins with hunters by then and become silent and call shy. Spot and stalk methods have also worked really well for some of my hunting buddies up there. I have found that early in the season there are large flocks of birds planted solidly on private ground but as the season progresses and other areas start to develop a more solid food supply, the birds move off of the private land and disburse along the public ground. I hope this helps and good luck!
Best,
