You can't say 'Indianapolis 500' without saying 'Indiana.' People from all over the planet pay attention when that race is on, which strengthens the case for saying that this is the most famous state for motorsports in the world.
One thing that the locals in Indiana don't race toward is retirement, because they'll struggle when they get there. Only two states in the USA have an average retirement income below $20,000, and Indiana is the worst of them.
