We have cougars here in southern Michigan... Jackson area... with enough sitings to believe we've got more than 1 or 2.
So why not Ohio?
We've had a sighting and photographs of a mother and a cub down here at the border of Monroe county (MI) and Lucas county (OH).
With so many deer running around, I wonder when the wolves will show up. There building quite a population in the northern lower pennisula and there isn't a lot of population down the center of the state to dissuade them from migrating.
