That's fine lyb, feel free to usher yourself into that large segment of society that doesn't like what it doesn't understand. Grafitti is a part of Italy, whether you enjoy it or not.

I am also going to Milan. What is Peck's market? en where. I can not find any reference of that in my books.

Peck is a fantastic delicatessen shop. There's a restaurant, cafe too. Can't remember the name of the street, but it is very close to the Duomo. It is not a market.
