I will be moving from Seattle to the Dallas area. I am driving and plan on leaving Jan. 13, 2009. I will have a dog and two young men with me. What is the best route this time of year? Are there any numbers I can call that will give me weather information along the way? How many miles are realistic to cover in a day? I am getting nervous and thinking that I should just head south to CA and take 40 over instead of the more direct route. Please help!
