D.B.
We moved here from San Diego about three years ago, and make the trip back about once a year to visit family. It's about 24 hours road time, the first day entirely still in Texas, and unless you get off your main course there is not much to see. I'm talking about the southern route, (I20 to I10 to the 8). It's pretty straight and easy, but not much to look at. West Texas can be pretty desolate. The desert before you get into San Diego looks pretty neat, my friend calls it the place where God dropped rocks. I think the I40 route may be more scenic, but I'd be concerned about weather/road conditions that time of year. It's a treck, but we do it with four kids in tow every year so it can be enjoyable. It's an adventure.
