While in Louisville we went on the Louisville Slugger baseball bat factory tour. The building that houses the factory, museum and store has a huge replica bat leaning against the building outside.
Since the very early years major league players would have their signatures on their bats, as well as the ones sold to the public.
A bat vault contains bats from many of the legends of baseball.
Unfortunately photography was prohibited on the factory floor. I did however come home with a nice new baseball bat.
