Every Tuesday night during the summer, Seattle's Lake Union is covered with boats. The air horn sounds and the race begins. All sorts of vessels, from makeshift floating docks to 70-foot sailboats, mill about in every which way. It's the Duck Dodge, and there's nothing else like it in any city in the country. It's less of a formal race and more of a party on the water and has been a Seattle tradition since 1974. Boating rituals like these are central to Seattle's core. Opening day celebrations, holiday boat parades and crew regattas are all part of the city's cultural heritage. From pleasure boating to the commercial industry, whether a boat or house or a plane, if it floats it's apart of the history and culture of Seattle. Water is everywhere in this city, even buried in the namesake -- Chief Sealth -- and it's a part of everyone who lives here.
