Forty-thousand tons of rock salt meant for New Jersey's icy roads is currently banned from so much as entering the Port of Newark. The reason? A nearly century-old maritime law that requires shipping vessels to fly the American flag. Naturally.
This winter has been particularly brutal on the Northeast, which has been hit by snowstorm after snowstorm with barely any time to catch its breath in between. It follows that the winter has also been brutal on the Northeast's stockpile of rock salt, which is running in dangerously short supply. The (apparently still strictly enforced) federal law from 1920, however, stands firm. Flag or GTFO.
