Rex, I imagine the F1 crowd spent more per capita in tourism dollars but I don't know that it exceeded either the Brickyard 400 or Indianapolis 500. An economic impact study a few years ago showed the "500" and "400" ahead of the F1 race, which was fifth, with the Super Bowl and Daytona 500 also in the top five.

Yes, I used that number in respect to F1 attendance. F1 events don't come close to the Indianapolis 500 or Brickyard 400 in attendance.
