A crystal clear blue sky over San Francisco's urban landscape during the annual Fleet Week. The mingling of nature and city life is truly a spectacle here at Great Meadow Park. From the lively waterfront scene with boats and cityscape to myriad elements of city life like bridges, buildings, and urban transportation – the city reveals a multitude of faces to the observer. In this photograph, the tranquility of the scene is highlighted by the serenity of the water body, the leisurely-flying birds, and the calm expanse of the sky.
