"Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds." You recognize that as the official motto of the U.S. Postal Service. While it's chiseled in stone on New York's main post office, it was borrowed it from the ancient Greeks who coined it to praise their highly efficient and dependable messengers who, on horseback, always delivered the goods in spite of weather, wars and insurmountable odds. Over the centuries, man has experimented with many means of mail delivery. In the 1900s, cows hauled mail wagons in Europe. Here in the United States, believe it or not, in Texas, New Mexico and Arizona, camels were used for a brief period. In Russia and Norway reindeer still haul mail sleighs, and in Belgium one city even tried cats. Still, nothing beats the U.S. mail for dependability. Remember that as you drop off your tax return tonight. You can be sure it will get there no matter what, although you might be hoping otherwise. And that's the On The House tip for today.
