Louisville is fun to come to in April for the kick off the Ketucky Derby festival... It's called Thunder Over Louisville... Look it up on the internet if you want... We've got the 2nd largest fireworks show in the world... It lasts about 30 min and averages 700,000 to 1 million people each year... The Derby itself (I'm sure you've seen) is a big horse race here where people bet their arses off and try and win some money... Derby is the first Saturday in May every year...
