What to do in Southern Ohio for the club

We are having a hard time coming up with something new for the club to do in 2014 in Ohio. Amy and I ate at a 50's diner last year and thought we would hit it but they are now closed down. It should have something to do with cars or something we are into. Maybe a nice hour drive or less from downtown Cincy. Other than the drive in I'm at a lost for that side of the river. After the gasser rip down some of the gals were trying to figure all this stuff out but didn't come up with anything. We are still doing the River Run and will cruise up to the old drug store that has the soda fountain in the back. That will be fun but I'd like to find something new that everyone would like. WHAT IS THERE TO DO UP THERE?
