"The photographs are of Hurricanes, Tornadoes, Floods, Typhoons, Fires, Avalanches, Ice Storms, Blizzards, World Trade Center and Pentagon Terrorist Attacks, Earthquakes, and the Columbia Space Shuttle Disaster."
Of the 14 photos for Arizona, only one is of an actual disaster [right, Wenden, AZ, 10/21/2000 -- This community was flooded twice in late October when waters from Centennial Wash swept into town. Photo courtesy of U.S. Small Business Administration]. The rest are of signing ceremonies or similar.
