Tourists take a picture of snow falling in front of Rome’s ancient Colosseum, on Friday, Feb. 12, 2010. A rare snow is coating Rome, dusting church domes but making slick cobblestones treacherous. Rome was last dusted with snow in 2005. The last significant accumulation came in February 1986, when some 20 centimeters (8 inches) piled up, paralyzing the city. (AP Photo/Gregorio Borgia)
