Fellows,
Here on the Great Plains there is no barrier or fee for roaming the grassland with 458WM in hand watching for the return of the buffalo or for the 100 LB Tusker feeding on the Verdant plain. Each spring I venture out to walk the hills and valleys ready and able to deal with whatever comes to the front sight.
If indeed you want to shoot some actual Buffalo; yes there are some folks in my neck of the woods with with herds that they do sell shoots on. I have never checked into that but could if you so wish.
Best regards,
