This year's wintry weather means the demand for road salt has skyrocketed. Some communities call it a shortage. Trucks lined up Tuesday afternoon at the Port of Coeymans, from places near and far like Buffalo, New Hampshire, and New Jersey. There’s more to this apparent shortage than you may expect. Dahn Bull is the highway superintendent for Clifton Park. He says the main reason for the shortage is just the frequency of winter weather we have seen so far, even though most have been seemingly minor.
