This view to the east is on a pier in Lake Washington owned by the City of Renton. The pier is is attached to a boathouse that used to be part of Boeing's Renton Plant. Up to the early 1980s the boathouse was used to support the testing of the hydrofoil boats that were built in the final assembly building in the distance. Yes---Boeing built boats! (Do a Web search for "boeing+hydrofoil").
The large final assembly building is where all 737s are assembled. 757 airplanes were built there too. When I worked in the assembly building in 1980 (on the boat program), there was not a single window in its exterior walls. We called our work “submarine duty.” Times have changed.
This is typical for winters in western Washington: long periods of gray days with light-to-moderate rain. It is too depressing for some people; folks that are used to lots of warm, sunny days would go crazy here.
