Not trying to deter you from WI but if you live in southern Ohio why wouldn't you head up into MI? As far as Wi, if you get above I94 you should be able to find plenty of lakes with good ice. I live between Milwaukee and Madison and most of the lakes still have 4" - 5" (some more, some less) of ice even after this warm weather and rain. Make sure to bring a spud bar with you and stop in to the local bait shops and ask questions. There are open spots on fishable lakes so just be careful and treat the lakes like early ice.
