We have a strong appreciation of Rome from our two days here. We wandered through Piazza's and walked to the Vatican City.
St. Peters Bascilica is grandiose! We could literally take hundreds of pictures. Saint Peters Square was massive.  We could imagine when it is full of people, though there are plenty of tourists about even in September. We wandered through the Vatican City to the Sistine Chapel, and were again in awe even after 30 years. We couldn't imagine trying to value that real estate, as well as the artwork and gold.  
We took a break at a small cafe in a lane for a glass of vino. Pizza is better in Canada. Then on to the Spanish Steps. The number of tourists here is mind boggling. Lots of high end fashion and no shortage of tourist vendors. The pace should become a little quieter tomorrow when we venture towards Tuscany. Driving will be interesting. Being a pedestrian in Rome has it's hazards. It's taking your life into your own hands. Even at a marked crosswalk it becomes questionable whether the driver will stop. You can't hesitate otherwise they will keep on driving qto try to beat you. Lots of mopeds and Vespa's.
