Hall County Fire Services staff pushed four new ambulances Friday into their new bays, a ceremony from a time when a pumper truck’s horsepower was in the single digits. “It’s kind of a symbolic gesture, on its first day, to have a pushing ceremony from the guys that are actually going to be riding in the truck,” Capt. Zach Brackett said Friday. In the earlier days of fire departments, the pumper trucks were drawn by horses to each call.
