- "Back Home Again in Indiana"
This song has been sung on the morning of race day every year since 1946.

It started because Louis Meyer drank milk out of habit and happened to do so in Victory Lane in 1936. The Milk Foundation made it tradition.
- the trophy
This trophy has been given to the winner of the race since 1936. It has the face of every winner since then on it. In the 1980's the last space was filled so they added a base to the trophy so they could fit more winner's faces.
