Tell your son to exit I-10, stay on the feeder until he finds a road going north, and take back roads that go north and west. He fan orient himself by keeping the sun either to his right or behind him.
Plus, eventually he'll find a service station where he can buy a big road map and figure out a long route.
Back roads will take awhile, but they're better than stalling out on 10.
We tried going down Fry to 529 this morning to avoid the traffic on 10 and 290. It is bumper to bumper there and someone just called in on Channel 13 to say that there is no gas on this part of town. We are waiting until later this evening with the hopes that 1)the storm shifts or 2) the counter flow lanes clear up the traffic problems.
KPRT (2 - NBC) are going to do a segment of what each county should expect to experience. The mph winds, rainfall, etc. Coming up shortly.
It took me 8 hrs + to go from Houston to Austin, leaving at 3:00 PM. My son's room mate bought a map of east Texas, left at 4:30 from Baytown (further than I had to go), too back roads and was in Austin in a little more than 4 hours.
But that was yesterday ... it might not work as well today
