as seen from the picnic tables of the wonderfully named Howard & Minerva Munch YMCA. If you look closely, you can see that there are, in addition to the main suspension cables, four stay cables running at an angle from the top of each tower to the deck (i.e., the roadway surface) of the bridge (here is a clearer view of the cables). The stay cables were installed, as were some since-removed stiffening trusses, after the similarly designed Tacoma Narrows Bridge collapsed spectacularly into Puget Sound amid a steady 40-mile-per-hour wind in 1940, the year after the Whitestone opened.
