The first day of Venice officially as a museum/theme-park. Just a year ago the left-hand photo was an April Fool’s hoax. Today the other photo is reality: the turnstiles introduced just outside the station, to redirect tourist-flows. A temporary measure for the long holiday weekend, is the official message. But Venetians are quipping that the next step will be the introduction of key-codes for residents, and anyone who forgets the password will just have to spend the night in Mestre.
