Hey, Mr．and Ms．Unluckiness and Unhappiness! Terrorism, the war, the economic crisis and unemployment are at your door．Are you afraid of them? Well, don’t be! America is a happy land．The Smiley Face icon proves this in towns all over the country．
The tallest structure—the steel water tower—is often painted bright yellow, in a circle containing a pair of black dots for eyes and an upturned（朝上的）line for a mouth: the unforgettable smile．Most towns decorated their spheroid (or cylindrical) water storage tanks in the 1970s, when Smiley was still conceptually fresh．As a "safe" counterculture symbol, with absolutely no bite, the Smile Face water tower was a low cost way to radiate sunny greetings to travelers and locals．Calumet City, Illinois claims to have been the first, when 8-year old resident Kim Fornero sent a letter to the city council in late 1972 suggesting a smile face would be more fun to look at than a plain old water tower．
In the 1980s, with the paint on the water tower fading, residents of Calumet City decided to make the face their own．They repainted the tower, and a Happy Cook Restaurant and Smiley Face Inn appeared on the highway outside the town, ready to make you smile! Local businessmen printed the Smiley icon on their business cards, and displayed Smiley Face souvenirs in shop windows．
By the late 1990s, the survival of the Smiley Face water tower was assured．It didn’t matter why the face had been painted there—it was now a part of history．In May 2009, the town again celebrated its Smiley Face water tower as a symbol of hope for a better tomorrow．
