The haunting melody of the ferry MV Puyallup, recorded at midnight last night as the chill air of Puget Sound blasted the railings. I met a crewman who shared my fascination with the sound... He described how small holes drilled to add clamps to the railings caught the air like flutes. The long pipes of the railings act as resonators, reverberating through the windward hull.
