The 2008 Democratic National Convention will be held in Denver, Colorado this August and is fast approaching despite the party's lack of a presidential nominee, yet.
The 2004 Democratic National Convention was hosted by the city of Boston, Massachusetts. Police presence and protests were significant during the July 26-29 event where keynote speakers included John Edwards, current Democratic presidential candidate Barack Obama and then Democratic presidential nominee John Kerry.
In 2004, a free speech zone was established at the Boston site for political activists, but others sought more public areas to exercise their freedom of speech. The photograph below captures protesters demonstrating in Boston's Faneuil Hall.
In 1996 the Taco Bell Corporation announced that it had bought the Liberty Bell and was renaming it the Taco Liberty Bell. Hundreds of outraged citizens called the National Historic Park in Philadelphia where the bell was housed to express their anger. Their nerves were only calmed when Taco Bell revealed, a few hours later, that it was all a practical joke. The best line of the day came when White House press secretary Mike McCurry was asked about the sale. Thinking on his feet, he responded that the Lincoln Memorial had also been sold. It would now be known as the Ford Lincoln Mercury Memorial. 
In 1974 residents of Sitka, Alaska were alarmed when the long-dormant volcano neighboring them, Mount Edgecumbe, suddenly began to belch out billows of black smoke. People spilled out of their homes onto the streets to gaze up at the volcano, terrified that it was active again and might soon erupt. Luckily it turned out that man, not nature, was responsible for the smoke. A local practical joker named Porky Bickar had flown hundreds of old tires into the volcano's crater and then lit them on fire, all in a (successful) attempt to fool the city dwellers into believing that the volcano was stirring to life. According to local legend, when Mount St. Helens erupted six years later, a Sitka resident wrote to Bickar to tell him, "This time you've gone too far!" (photo via 
On April 1, 1978 a barge appeared in Sydney Harbor towing a giant iceberg. Sydneysiders were expecting it. Dick Smith, a local adventurer and millionaire businessman (owner of Dick Smith's Foods), had been loudly promoting his scheme to tow an iceberg from Antarctica for quite some time. Now he had apparently succeeded. He said that he was going to carve the berg into small ice cubes, which he would sell to the public for ten cents each. These well-traveled cubes, fresh from the pure waters of Antarctica, were promised to improve the flavor of any drink they cooled. Slowly the iceberg made its way into the harbor. Local radio stations provided excited blow-by-blow coverage of the scene. Only when the berg was well into the harbor was its secret revealed. It started to rain, and the firefighting foam and shaving cream that the berg was really made of washed away, uncovering the white plastic sheets beneath.
In 1981 the Daily Mail ran a story about an unfortunate Japanese long-distance runner, Kimo Nakajimi, who had entered the London Marathon but, on account of a translation error, thought that he had to run for 26 days, not 26 miles. The Daily Mail reported that Nakajimi was now somewhere out on the roads of England, still running, determined to finish the race. Supposedly various people had spotted him, though they were unable to flag him down. The translation error was attributed to Timothy Bryant, an import director, who said, "I translated the rules and sent them off to him. But I have only been learning Japanese for two years, and I must have made a mistake. He seems to be taking this marathon to be something like the very long races they have over there." 
In 2002 the British supermarket chain Tesco published an advertisement in The Sun announcing the successful development of a genetically modified 'whistling carrot.' The ad explained that the carrots had been specially engineered to grow with tapered airholes in their side. When fully cooked, these airholes caused the vegetable to whistle.
