33 on Sunday: Two friends struggle to advance to the pinnacle of American auto racing.

There was a time...

...when the Indianapolis 500 was aired only on radio.

...when pit crews hammered wheels loose during a pit stop.

...when men raced in the Indianapolis 500 and drove the next day at a small dirt track.

...when race cars were transported on open trailers for all to see.

Do you remember that? This is a story of that time.
