We are south of Cheyenne a few miles and just 2 miles into Wyoming.
Terry Bison Ranch is a real ranch raising bison and they have a campground and several building to replicate the frontier experience.
They offer train and horseback rides through the ranch and try to be a mini Six Flags but that part of the business seems to have fizzled out. Could be a different story during Cheyenne Days.
The feed lot for the ranch sits several hundred yards (thankfully) behind the compound but I thought there might be bison grazing in the pasture beside the highway.
No bison in the pasture close enough to take pictures, just a couple camels.
