I'm counting down the days until the 100th running of the Indianapolis 500.

I'm not a race fan in the fanatic sense. I've only been to the Indy 500 a handful of times. My memories center around listening to the race on the radio in the backyard while filling out the leading laps grid from the Indianapolis Star.

I do love Indianapolis, tradition, and most of all a theme! Each day I will share a memory or tidbit of history.

And since I do love a theme, I feel like I need to start at 100 for the countdown, so let me catch you up. 

Let's take a quick look at the end of the 1989 race. 

Emerson Fittipaldi and Al Unser, Jr. were battling it out. Unser was able to pass Fittipaldi with three laps to go.

With two laps to go, Unser approached slow traffic. Fittipaldi closed in, and on the backstretch, pulled inside Unser. Running side-by-side in turn three, Fillipaldi drifted slightly high and the cars touched wheels. Unser spun around into the wall. 

As the yellow flag came out for the last lap, Unser stepped out of his car unhurt and walked to the edge of the track to give Fittipaldi a thumbs-up as the pace car escorted Emerson to his first Indy 500 win. What a great sport!

When IMS replaced the walls, Unser asked if he could have piece. They offered better than that - He got 80 feet of the track`s historic wall — including the section in Turn 3 that he plowed into after touching wheels with Fittipaldi.

The wall now stands at the entrance to the Unser Racing Museum in Albuquerque, a great reminder of the obsession legacy down through the Unser racing family.
