Wouldn't you love to sit all day on the steps of a bridge and watch all the canal activity below? Don't plan on it because foot traffic is often so very heavy on most bridges that signs are posted to tell you "No Sitting on the Bridge". Also, keep to the right on a bridge or you might get mowed under by oncoming walkers. But such is Venice where bridges are a key way of life and unbeatable places to quickly snap wonderful photos of gondolas gliding below.
