I forget that you can go through Utah..
When I picture the drive, I picture it in an L shape.
Down the coast of California,
over through Arizona, into New Mexico.
Going that route took me 3 1/2 days.
Of course, Im not the fastest driver in the world.
Not going the route I picture, Im sure it is an easy 2 days drive, or less.. if you ignore lights, stop signs, speed limits ...
