Why not, any illusion of grandor is long gone. Indy doesnt carry 1/2 the clout it used to have, neither does Indycar racing or USAC. Used to be when I was growing up Indy racers used to be hero's, not so much now days.
The 500 outdraws the 400. so it appears that the Brickyard is the race that nobody has interest in. Send the other two races back to IRP. Rather slim crowd at the Speedway today for the sports car race.
