What was the airport impact?

A NASCAR track with that many seats gives rise to a TFR (stadium rule)
restricting aircraft traffic unless they are in contact with ATC. Arlington,
being an uncontrolled field except once a year during the EAA fly-in, would
be effectively shut down.

Someone with the text of the appropriate regulations is welcome to correct
and or refine this, but AFAIK, that is the gist of the impact.
