FYI, I have read several times, people quoting Niagara Falls as one of the Seven Wonders of the World. Unfortunately it isn't. Many feel that it should be. The seven listed as the Seven Wonders of the Ancient World are: Great Pyramid of Giza; Hanging Gardens of Babylon, Statue of Zeus, Colossus of Rhodes; Temple of Artemis; Mausoleum at Halicarnassus; Pharos of Alexandria. There are also sub-lists that have just 'Wonders of the World', there is Natural wonders, Human wonders, Man Made wonders, But Niagara isn't anywhere to be seen. It is however thought to be the most powerful waterfall and most beautiful.
Should we start a petition? I would love to see it on the Natural Wonders List. Most who visit say it is "Wonderful"!!
