I would think people would know better than to take a major route that would most likely be clogged.......
My parents left Victoria at about 10:00 this morning, they just called from my uncle's house in Kilgore after 9:00. It's usually a 6 to 7 hour drive, took them about 11 this time. No big panic though, didn't have too much trouble getting gas. Of course, my father is smart enough to avoid the big towns and stick to the rural highways.
