Hi,
Thanks for the advice.
I am going to give more info so that might help.
It is one way trip.
I have done some research to find places that are "must sees" for me and here are some of them:
Grand Canyon, monument valley, Saguaro National Park, Kartchner Caverns State Park
make a one day loop for Canyon de Chelly, Painted Desert, Petrified Forest.
My interest is more towards scenic roads and sites and nature in general.

After Arizona I could either head towards 1)California and Oregon or 2) Utah and Idaho.
Which one route has more to see?
Weather, and road condition since I am riding a motorcycle is also a consideration.
Thanks again for your help
