Thankfully our tiny little Fiat rental car got upgraded for free to a Alfa Romeo 159 wagon. Its little turbo diesel engine and phenomenal handling got us from Rome to our new destination in Siena with little problems. From the terrain, however, we should have gotten an AWD truck...as the bottom of the car scraped on several gravel roads.
I will have to get a flickr account so I can post all the photos that I took - the scenery is more beautiful than one can imagine. We are currently in Siena proper, a history town with lots of shops and culture and magnificent architecture and history.
It beats Rome hands down...sorry, Roma - Siena is our new favorite and we have yet to visit Florence!
