US Postal Service data suggests significant population decline in San Francisco
Currently live in Chicago, visited San Fran a few months ago.  It's eerily and completely dead.  Like no-cars-no-people-no-life-at-all-dead.  Compared to Chicago where there are thousands of people going about their day (walking, biking, driving).SF is much more low rise though.  Could just be all the commuters that no longer commute that contributed to the feeling of... apocalypse.
