Anita and Jonte are accompanying me for the first 3 1/2 weeks - the USA/Mexico leg. We left Adelaide on May 18 flying to Los Angeles via Sydney, and onto Phoenix, Arizona. Hired a Ford Escape and overnighted in Phoenix. Flying over so much desert and so many mountains, we found Phoenix to be surprisingly large with a population of approx 4.2 million! (making it the 14th largest metro area in the US and being home to more than 2/3rds of Arizona's population).............after all that flying and sitting in airports - still May 18!!
