Skye Graham | CollegianHillsdale has suffered more snow-related car crashes this season as the county faces historically low temperatures, according to the Hillsdale County Sheriff’s Department. The Hillsdale County Road Commission said its drivers are working hard to clear the roads during harsh weather in a Jan. 25 Facebook statement. The shortage, Baxter said, is also driving up the costs of salt. “The salt shortage has been causing quite a bit of a mess for everyone,” Baxter said. “It’s a tough, demanding job, but Hillsdale has a great group of guys that rise to the challenge in these poor weather conditions,” Baxter said.
