I have been working this Saturday for a few hours. But as the library (my current working place) had only opened from 12pm-5pm, I had some time to visit the nearby Seattle Street Fair which is pretty big. Lots of bands playing, beer gardens, very -esoteric-, err, alternative stalls offering anything from fried ice cream to hand reading sessions. Lots of people too and I was having a blast just wandering along the street.
On a completely unrelated note: I am starting to become a Teriyaki expert, it seems every second restaurant offers it around here. Yummy.
