Rome - lots of history here. The Pantheon, the Colosseum and the St Peter's Basilica in the Vatican City - I wonder how the Swiss guard at the Vatican manage to survive in summer with their rather heavy and elaborate costume.
I thought Kenya had bad driving. Italians have this craze for speed; taking a ride on a taxi can be a scary/thrilling experience especially if the road is somewhat clear. Powerful motorbikes and scooters that seem to be turbo charged seem the order of the day. Not many people ride bikes like in other cities in Europe.
The pizza is great :) after all this is the home of pizza. And the ice cream is top notch. (especially from Blue Ice)
