This post is dedicated to the bike. To this marvellous and bio-natural means of transportation. When in Bologna, I usually go biking, or walking: ten years ago, when I started the university, lots of people used to go by bike, now everybody moves around by car, in spite of limited traffic areas, high pollution levels, and so on.
My brother, who lives in Milan, always says that milanesi (inhabitants of Milan), can even survive without air. But not without car.
