Take the NE 8th Street exit (stay in far right lane), and keep to right (East) when the exit lane splits. Merge onto NE 8th Street and continue eastbound for approximately 1.7 miles.
Turn left onto 140th Avenue NE (at the NE 8th/140th Ave NE intersection there is a Walgreen's drug store to the right and a Shell gas station ahead on your left).
The WSCPA is in the second office building on your right. It is a two-story, light brown building.
