Sulk!

Some of you said you'd like a mystery photo. I gave you five and nobody's having a go! The last one is the bridge I posted on 24 January. The middle one should be familiar to anyone who has eaten at La Zucca trattoria/osteria. The first one is in Cannaregio, over a rio known by two names. The second one is on the boundary between two sestieri. If I gave you the names, that would make it too easy. The fourth one is in Santa Croce (that's obvious as you can see the sign for Parrocchia San Cassan), and shouldn't be too hard to find.
