Adrift from Simon Christen on Vimeo.

On chilly autumn mornings, the fog rises from Pittsburgh’s rivers and envelops the town.

Our fog is nothing to the thick fogs on northern coasts.

In San Francisco, Simon Christen took time lapse photos of moving fog and wove them into his beautiful video:  Adrift.
