This time lapse video from January 30-31, 2012 has multiple things going on. It’s also a tale of San Francisco’s urban recyclers and the story of two buildings in the Mid market area and how their Recology bins get taken apart all night long creating such a mess that the rats come out. You can actually see the rats come at at the 5 minute mark almost center of the video, which is about 4am
