We left Nashville on the morning of Day 5 and headed north along I-65 towards Indianapolis for a one night stay in that city. We had to drive through a section of Kentucky after leaving Tennessee and stopped in Louisville to see a few sights. My brother is a big baseball fan and we were able to tour the Louisville Slugger Museum and Factory where they make the famous baseball bats. Joe was like a kid in a candy store, buying several souvenir bats for his grand children. The company offers 30 minute tours every half hour. It was very informative and a lot of fun. We also stopped at the Muhammad Ali Center and drove to the cemetery to visit his grave site. My dad was an amateur boxer and a big fan of Muhammad Ali. When we were children, he took me and my brother to see a satellite broadcast in New York City of one of Ali's boxing matches; it was the first match Ali fought after he was allowed to return to the ring following his refusal to serve in the army during the Vietnam War. I wanted to pay my respects to the man who made boxing so popular during the 1970s when I was growing up. From Louisville we crossed the Ohio River into Indiana and drove straight to Indianapolis. We had tickets to see the Indianapolis Motor Speedway Museum located within the famous track where the Indy 500 is held. When we arrived in Indianapolis a terrible storm was hitting the city and the race track was actually closed (due to tornado warnings). We spent the night in a pretty run down Motel 6 not far from the speedway. On the following morning we visited the Indianapolis Motor Speedway. It was Saturday, the weekend before the Indy 500, and the track was having qualifying rounds for the big race. We spent 1.5 hours in the museum, which was awesome, and then watched several of the qualifying runs on the main track. The very first racing car that I tried to photograph as it zipped by at more than 200 miles per hour hit the wall and crashed. I actually got a picture as the crash occurred. Luckily, the driver was not seriously injured. Within 15 minutes of the crash the ground crews had already removed the twisted racing car from the track and the qualifying rounds continued. It was pretty exciting to witness. We left Indianapolis in the middle of the afternoon and drove north to Green Bay, Wisconsin, which was our next stop on the road trip.
