A young man and a woman enjoy swimming in flooded St. Mark's Square in Venice, Italy, Nov. 11, 2012. High tides have flooded Venice, leading Venetians and tourists to don high boots and use wooden walkways to cross St. Mark's Square and other areas under water. The water level reached a peak of 58.66 inches, below the 63 inches recorded four years ago. Flooding is common this time of year.
