I go to Kings Island, (and/or Cedar Point) every year, but that's a guys trip.
The aquarium sounds good, as does the Reds hall a fame. I will try to do both time permiting.
My Brother in law lives in New Albany, (the Indiana side of Louisville) so we are in Louisville 4-5 times a year, and I'm ashamed to say I have never taken my kids to Louisville slugger museum..
We are heading to Louisville for a quick family visit after Cincinnati, on our way to Mammouth Cave, so this might be the time to do it.
Thanks for all the info...I enjoy this forum a lot, Reds fan or not...
