And indeed,I- 20 through Texas...but heading west,
from CA, you would be on I-10, until the split with I-20, which would keep you
more north that I-10. I had forgot, as I just think of I-10, as I used to take
it between L.A. and Phoenix a lot when I lived in CA. I'd still go I-40,
but beyond Oklahoma City, heading east, I have not seen it, or traveled that
direction. But, one tends to often chose routes they are more familiar
with, and I know I-40 between OK City and into CA well. I can drive from Flying
J to Flying J, and know I can get in and out for fuel with the rig, know what
rest areas have areas to unload, and other spots I can pull over to park and
sleep for awhile.
