I think of Seattle as having a gray-green heart. It is city shaped by nature, a city of snow-covered mountain, sparkling glaciers, and blue lakes. It has been called '' America's Most Dynamic City,'' the '' No. 1 City of the Future,'' and '' America's Athens'' by three major U.S. publicatons. But why has a town that is so far away from the nation's major power centers attracted so much attention?
