I found it.

It's about 3:30am here in Austin, Texas. I'm sitting here by the ticket counter waiting for the airport to literally open. Evidently it's closed now. The doors to the outside are closed; there are gates blocking all the entrances to the terminals. And I'm the only one here who isn't working.... Anyway, during my visit to the McNay Modern Art Museum, I found the Matthew Maconahay accent. Wonderful! It was exactly where Mr. El Paso said it was! Lo and behold, it was a man from Fort Worth. Spot on, Mr. El Paso man. Spot on!
