After a fire call, our firefighters were hanging around before going home. 2 State Troopers were chasing 2 motorcycles. Since our FD is located at an intersection, the troopers saw the opportunity to end the chase since the bikers had to slow down to turn. 1 of the motorcycles entered the fire dept parking lot and struck a parked Fire Truck head on, leaving the motorcycle stuck in the front bumper. One of the troopers patrol cars slid on the wet grass and stuck the metal storage building. Taught us to ALWAYS be on the alert!
