The corvette museum is nearby,.and you can tour the plant also. I assume you already have a place to stay/camp, but if not, we usually camp at Diamond Lake Resort in Owensboro, KY. It's about over an hour from the attractions referenced, but a nice campground. I did a rally there for another forum earlier this year, and we go there for some of their events. I think there's also another cave tour in the area, too. Good luck and safe travels.
