Found in the Georgetown neighborhood near the hipster restaurants and Fantagraphics headquarters. I pulled over on my way to Costco when I glimpsed this between buildings. I wandered nearby and pushed my camera between the gaps in the surrounding green fence.
When I tried to look into it, all I found was an empty University of Washington record online (http://pcad.lib.washington.edu/building/10873/) claiming that "The logo painted on the side of the building is visible from a long distance."
