Check the above link.
The Grand River Wildlife Area is probably exactly what you're looking for...there are a few others within 30 to 60 minutes that are also excellent.
You can also download free maps, or write to them and they'll send them at no charge. I think they'll only send 2 or 3 at a time, so you cannot order too many at once if you want them mailed to you.
The Ohio Division of Wildlife is a great outfit.
Hope that helps.
