We just came back to Austin from Venice on Tuesday. We left Venice at 4:45 a.m. and my memory is that we made it to Houston about 1:00 p.m. So that would be a total of about 8 hours. We stopped a couple of times for coffee and some re-arranging of the trailer. Of course, we avoided the worst part of New Orleans traffic around sixish, and a lot depends on N.O. and Houston traffic. We only found washboard roads in two stretches--one was somewhere in the Atchefalaya-Baton Rouge run (I wasn't driving so I'm not sure exactly where), and the other down south of New Orleans. Neither one was more than a few miles.
