I love the energy of San Francisco as it transitions on any given Friday from afternoon to night. Cue Karl the Fog, lurking to the west. Next the twinkling of lights along the hills and bridges. A sweetness in the air. Layers of clothes ready for varying micro-climates. And people watching. Where are they going? Who are they waiting for? What are they thinking and where are they from? An interesting dynamic develops between the restless commuters, excited tourists and out-for-drinks crowd. An intensity of sorts - simultaneously frightening and alluring. You could be murdered. Or fall in love.
