Plan to go through Amarillo, TX and go to the 'Big Texan' steak house, you will thank me later. Just west of town there you will see the 'Cadillac Ranch' on the left.
There are tons of Route 66 sites to see.
As mentioned above, The Petrified Forest/Painted Desert was wonderfull! We wished we had started when the gates opened! We could have spent the day there.
Meteor Crater is a must too!
My brother took the train trip from Williams, AZ to the South Rim, paid $81.00 and would have been glad to pay more! (You get about 3 hours at the rim.
Make sure to walk down the 'Bright Angel' trail until just past the first tunnel. We had a Bighorn Sheep so close I could have petted its nose.
Since you are so close to Tucson, please go to the Pima Air Museum just east of town. My wife who is not big on planes LOVED it.
There are a couple of Air Force One planes there including the small on President Kennedy had done so he could get to Hyannis Port. I will leave the rest of that story to the docents!
Then on the way out of Tucson there is Texas Canyon. Imagine a rock the size of your house perched on a rock the size of your car!
Lots of stuff to see!
