How is it hanging? They're just showing off. Change of scenery. Do you know how many cliché about air we use on the Colli Piacentini? None. From us the air is breathable: when you approach the wine and food shops in a medieval village, while you are on a hike in the woods, or after a dip in a high-altitude stream. On the Colli Piacentini you can also taste the air.
