To give you some perspective, see the town of Sealy on the West side of Edgars map?
That's about 80 kilometers from the center of Houston.
Austin, where I live, is another 190 km West and a little North of that.
To get from Austin to El Paso, at the far West of Texas, you'd go another 925 kilometers.
Funny story from when I was working. A co-worker was flying in from I think Chicago and was supposed to be at a meeting that started at 9am.
Around 9:30 I called him to see if he had gotten lost on the way from the airport.
He said no, he had decided to fly into Dallas/Fort Worth instead, and that he figured it would probably add on another 1/2 hour to his drive, and that way he could see some of Texas.
I told him I'd see him at lunch. He thought I was kidding.
With traffic and all he finally got there around 2pm. We always laughed about that afterwards, like for years.
