SEDRO-WOOLLEY — The Sedro-Woolley Fire Department is making the best of a bad situation. In May, the city’s newest ambulance was hit head on by an impaired driver, and was totaled. The ambulance had been in service for about 18 months. While the chassis of the ambulance is no longer usable, what is known as its box — where patients ride and gear is stored — was deemed sound. On Wednesday, the Sedro-Woolley City Council gave its approval to remounting the box onto a new chassis.
