Fog-The San Francisco Treat

The city is quite (in)famous for the fog that rolls into the whenever it feels like. Today when I left the office, it was a sunny and cloudless blue sky. There was nothing to portend as I headed out to a customer site. While in downtown, buildings seem to phase in and out of view as they succumb to the encroaching mist. Buildings disappear when you increase the distance between them and yourself. As noted, this was unexpected as skies were clear when I left the office. The bay area is known for its micro-climates but I did not imagine the mini-micro-climates within the city limits. However, as noon approached, the mid-day sun chased away all traces.
