Red Fox are actually pretty common in Ohio, but their habits make them very seldom seen. There was vixen with a litter of kits that would come up across the road from our driveway. The lady who lives two doors down would leave food out for them.
As for wolves, no, there are no wild wolves in Ohio. The size of a wolfpack's range would inevitably bring them into contact with humans. That's over and above the fact that evidence of wild wolves would be easily found.
BTW, regional extinction can also mean general extinction for subspecies. There are several subspecie of lions in Africa, for instance. The Swamp Lions that were the focus of a Discovery Channel series are one example. Europian Lions, Turkish Lions, etc., may have been subspecies that are now completely extinct.
