If you're in the Seattle area, this would be a really good day to pick up a Sunday Seattle Times, as it contains a handy and beautiful special section about the brand-new Olympic Sculpture park. Pull it out and take it with you when you wander around all the great new art and open space!
Whether or not you're in the Seattle area, you should look at the
online presentation of that plus other material, including an audio file you can load onto your favorite MP3 player to take a narrated walking tour of the park whenever you get the hankering.
