Rio Grande to Patagonia is the author's tour, 23,282 miles, 27 countries, 54 customs inspections in a year of living in a suitcase. This is the unusual rather than the usual inspection of foreign countries, sometimes glib, with many practical suggestions about traveling, and of interest for an overall picture of our neighbors to the South. There are interviews, conversations; there is hotel as well as apartment living; there is, necessarily, much of air travel and what to expect as a passenger (the car was left in Mexico); there is attention to important tourist sights as well as characteristic differences between the countries- with the author never taking his eyes off the Japs one minute. He interprets social as well as political implications, describes geographical as well as psychological climates. A pert, as well as a pertinent, travelogue.
