For the most part I hate Thunder over Louisville-I went my freshman year at UofL & it was so incredibly boring. If you are going to go see the fireworks make sure you show up as late in the day as possible. Sitting all day watching planes fly around in the sky is not how I like to spend my Saturdays!
Now, as far as the Derby goes, its a great experience. Everyone should go & sit in the infield at least once. And don't forget to bring a flask.
