Comments about routing

It looks like I'll be heading through the State of Texas on my way to Tucson, AZ. If all goes as planned, I'll take roads that parallel I-30 to Dallas where I'll visit family. From there, I'll follow as close as possible to I-20 till I reach I-10. I believe I can parallel I-10 all the way to Tucson. I should be leaving Little Rock, AR on Wed. 9/26/07 pending weather.
