I wasn't really even going to post about this since Blair already did such a fine job of it here and at Flickr here. She inspired me to finally go see the downtown branch of the Seattle Public Library and it was so very worth it. It's an extraordinary public space. I would recommend going there with children, in particular, and exploring it with them. It was a treat to get to do this with E, to just follow him and to go at his own pace.
Things I heard while there: "Lets see where this takes us!", "How are we going to get back down there?", "I see the city and cars and motorcyles down there.", "These are weird stairs.", "Down, down, down. It was a long ways down!" We even found areas where the stacks were still empty, and a corner where piles of old, bound, newspaper publications were stacked taller than E himself.
Afterwards: "My favorite part of the library was doing puzzles. No, it was the [15 second, silent] puppet show I did for you." Country boy that he is, he was just as easily impressed with putting coins in the parking meter, underground garages, taking elevators, and checking out manhole covers in the sidewalks.
