Houston tips?

Thanks Texan, I have been looking at the map and considered going back up the 124 and over from there at 10. It looks to be a 7 hour day so I don't want to add too much in the way of miles and time. If I head up 45 and hit the 610 to 290 and the 6 at about 9-10am would that miss the majority of rush hour? I hope so.
