They've got gridlock going **North**...but you can probably still drive on the beach South from Galveston down to Corpus Christy or even to Brownsville, and I-45 South to Galveston is probably empty right now.
The masses are headed North. West and/or South far enough will get Texans away from that storm.
Roger that. In fact if I was in Houston, I'd probably be thinkin' of running down the 35 (all along the coast - I'm CERTAIN there's no traffic), and trying to jog NW occasionally.
Aa ir looka right now, hangin' out in Corpus Christi for the weekend, and then playin' it from there, probably aint such a bad idear.
