Today is a day that my dad would have taken his hat off to and been very proud of. My dad was a rural mail carrier and took pride in his work and the folks that he met. Why would my dad think this day is cool is because today is dedicated to all postal workers.
The reason is because today is the day for Neither Rain Nor Snow Day
"Neither snow nor rain not heat, nor gloom of night, stays these couriers from the swift completion of their appointed rounds."
This slogan has long been attributed to the United States Postal Service, honoring mail carriers. In fact, the quotation was inscribed on the outside of the James Farley Post Office , New York City's primary postal location, which was dedicated on September 7, 1914.
As a result, September 7th has become known as Neither Rain Nor Sleet Day, or Postal Workers Day.
It seems the U.S. Postal Service has no official slogan. The "neither rain nor sleet" quote actually came from an ancient Greek work, Histories, by Herodotus. However, the saying has been unofficially linked to the U.S.P.S. for generations.
September 7th is a positively postal holiday, recognizing the devotion of those who deliver the mail, day after day, in all sorts of climates and conditions.
