The postal service is in trouble.  I’ve written about it before. The internet and email have critically wounded their revenue stream.  The USPS will be the Amtrak of our children’s generation.  But they are trying to survive and this photo shows an example of there willingness to experiment:

A mobile post office on a downtown streeet in Los Angeles.  Good Idea!  But it won’t stop the decrease in mail.  Eventually there will be so little volume that even the media and the politicians will notice.  But you will be able to say “I knew that.” because you read it here first.
