I was born in Louisville and still have some nephews there so it's always a nice stop to see relatives and bring back old memories. We were lucky this year that we hit town during the State Fair. We spent a day at the fair and had a blast. Janie had never been to a State Fair before and thought it was great. It's a huge fair! 
They have a Six Flags that is on the fair grounds so it makes for a really big deal. 
Louisville is also the home to the Louisville Slugger baseball bats (they have a nice museum at the factory) and Mohammad Ali (who also has a museum of his career).
