Deerman, even most of the beeks in Canada now overwinter their hives.
Ohio has a very healthy number of beekeepers, of which virtually none practice cull-and-replace. With the current bee shortage, most have now come to understand the importance of not killing bees, and the ease of overwintering (especially in your area) if the proper steps are followed. There is a lot of info out there on winter setups, but your area should be a pretty easy one for overwintering hives in.
I hope this helps.
