drive thru Colorado or Arizona

[debbi]

I am planning a summer trip ohio to Nevada and am tossing up driving back thru Colorado or Arizona. Any opinions on the more scenic route to take?

Why not route through Colorado/Utah westbound and loop south through Northern AZ/New Mexico eastbound and see a little bit of all of it?

The entire western USA is as scenic, magnificent and beautiful as any place on the face of the Earth. How can one determine whether one place is more scenic than another? Bob
