This could be copied in Some Southern Wisconsin's State parks with both elk and bison and If I'm not mistaken, I think there is A state park in Central WI. that already has a few buffalo...? Yep, sure enough, check it out.... http://dnr.wi.gov/org/land/wildlife/reclands/sandhill/bison.htm
Last time I checked, Madison is in Southern Wisconsin, and there are lots of State parks around here.
I already quit arguing. However, if you want to keep poking the bear, go ahead, this one's going to hibernation now.
