Neither snow nor rain nor ...*

Converting a wheeled vehicle into an over snow machine is not a new idea. This over snow conversion unit (on a 1923 Model T Ford) is on display at the Smithsonian Museum of American History in Washington D.C. The vehicle in the Smithsonian display was used to deliver the United States mail.

* (Trivia) Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds is actually a quote from book 8, paragraph 98, of The Persian Wars by Herodotus, a Greek historian. During the wars between the Greeks and Persians (500-449 B.C.), the Persians operated a system of mounted postal couriers who served with great fidelity. More than two thousand years later those words were chiseled in gray granite over the entrance of the New York City Post Office (James A. Farley building) at Eighth Avenue and 33d Street in Manhattan and became the United States Postal Service motto.
