Just last night I learned that we missed out on a bit of American pop culture that would have been interesting for the roadtrip. We never saw the movie "Cars" which, apparently, is based on the story of I-40 killing Route 66. This was our experience too.  Here are photos... 

We used a book called Road Trip USA by Jamie Jensen, which pointed us to towns, sights, cafes and oddities along the way. I got into the greasy spoon cafes along the way.

 This is the famous onion burger at Johnnie's Grill in El Reno, Oklahoma.

Joe and Aggies in Holbrook, AZ. 

Dinosaurs, dinosaurs everywhere.  Holbrook, AZ.

19 cents per gallon.

 We drove, a LOT.  Actually, I rode a lot and Sachi drove a lot. There is something about the little gas stations that seems so American.  It's like a little microcosm of the local population.

 From Route 66 we went north to the Grand Canyon and Zion National Park.  We posted some mobile blog posts from Route66 here and here.
