pps: they've also tried arguing that any airport capable of landing international planes is also a "border", so draw a hundred-mile circle around bigger cities in the interior as well ...
That's not even all of them. Those are international airports with commercial flights. It's finally changed its name to Terre Haute Regional Airport, but when I moved here, it was Terre Haute International Airport. It didn't have commercial flights then and it doesn't have them now.
In fact, as far as I know within the last 50 years or so, it's been private planes, chartered flights, military planes, cargo and Con Air to the federal prison. If you wanted to fly to Acapulco, you'd have to either charter or go to the real commercial airport in Indianapolis.
