SPRING GROVE – The salt trucks in Spring Grove are a little different from the ones that crisscross other small towns.

That’s because the anti-icing mixture being scattered across the roads was made in-house, saving taxpayers $30,000 over the past three years, said Matt Wittum, Spring Grove Public Works supervisor.

“A lot of municipalities use liquids with their winter maintenance, but the majority of them are either larger municipalities or if they’re using them, they’re just buying them from vendors pre-made,” he said.
