Where are good places to take a weekend motorcycle trip to, within 3 hrs each way, and leaving out of Cincy,OH?

I am looking for any place that has something fun to do or see that is within 3 hrs. of Cincinnati, Oh for a weekend motorcycle trip. We will have group of bikes (Harleys) and looking for neat spot. Would be nice to find a location that is biker friendly, maybe with popular biker activities or bars.
