I killed my Bison in Texas, however the ranch I hunted no longer offers archery hunts. It was low fence and about 20,000 acers but if you want truly wild then you have to go to the places listed above and it will be very expensive or a once in a lifetime draw. I do not know about the reservation hunts in South Dakota, not sure if they have fences or not, but might be the way to go. My hunt was no cake walk but not the same as camping out in the wild and finding the Bison and then trying to stalk them, yeah I had to find them but on a ranch it is not that hard. Once found then a stalk was planned and if they smell or see you, well you have to try and get ahead of them and plan another stalk but pretty much can be done in a day.
