I don't know any state parks you can hunt. Not sure of the Zoo status either. It is a very nice ecosystem that has been preserved. Just as my wife's uncle wanted. He is the one that donated all of the land for it. One thing that I think that is really neat is that as you leave the visitors center and hike up in elevation, not a great deal of rise but relative for a prairie, as you get to the top, there are crawdad burrows everywhere. And if you check some of the bison wallows that had held water, you can see where hatches have taken place and see thousands of very, very small sheds bleached by the sun.
