This past December, when my Venetian husband and I returned to walk the streets of Venice, we found them almost devoid of tourists. It seems that the few hours of exceptional acqua alta that they'd had at the beginning of the month had scared most of them away. It was peaceful, yet unsettlingly eerie... a city out of time.
If you'd like a taste of that profoundly rare experience, here's a lovely video of a touristless Venice. Enjoy!!
