Last night I finished reading American Heartbeat: Notes from a Midwestern Journey which he wrote about a trip he took in the US, driving from the Canadian border to the Mexican via I-35 in the mid-1970s. Being that he's British he looked at the Midwest as an outsider, and his writing seemed pretty even-handed to me.
Yes, I know that it's now a book forty years out-of-date, but it certainly evokes the era in which it is written. Heck, I checked online and some of the restaurants that he enjoyed greatly still exist. I really enjoyed this book as much as any of his works that I've read. Recommended.
