The Seattle World's Fair of 1962 was called "The Century 21 Exposition." The theme was very much about the space age and the wonders of the world we would know a mere 38 years hence. It was a big success by almost any measure. It left a large public park and an opera house and an arena that five years later was home to an NBA franchise. And the Space Needle, of course. The Pacific Science Center, which started life as the U.S. Science Pavilion, is an architectural masterwork by local guy Minoru Yamasaki, who later designed the World Trade Center towers in NYC. It's worth one's while to pay it a visit, even if one never steps inside. The arches and reflecting pools are are fresh as they were 56 years ago. Oh, and Elvis made a typically forgettable Elvis movie there.
