This image, "Ebb Tide, Astoria" was previsualized.  However, what I hadn't pre-visualized was the constant rain.  Working in the pre-dawn darkness, I had to hold an umbrella with one hand while setting up tripod and camera with the other.  Astoria Bridge (4.1 mi / 6.5km long) spans the mouth of the Columbia River between Astoria, Oregon and Point Ellice near Megler, Washington. Construction was started in 1962 and completed in 1966.  Nikon D200, 17-50mm/2.8, ND filters.
