Hit some of Route 66 in Arizona if you can. Kingman has a good museum with lots of petro stuff. Oatman if off old 66, and pretty cool. Time it so you can see one of the old time cowboy shootouts in the middle of main street. Oatman is SMALL, really gives you a feel for what old 66 must have been like back in the day. You can buy some carrots in town and feed the wild burros if they wander in town, which they almost always do.
You can actually drive the length of old 66 quite aways through Arizona if you map it out. Lots of websites out there to help. That's what I did.
I'm heading back out next month and can't wait. Need some sun and warmth.
Have a great trip!
