FOX 5 spent a few hours riding along with firefighters from Engine Company 10 and Truck Company 13 in Northeast.
Among their many calls for service was to a report of fire at a Capitol Hill restaurant. Nobody was injured in the fire at La Lomita on Pennsylvania Avenue, SE.
A nearby D.C. Water crew was busy repairing a broken water main.
A D.C. Fire and EMS spokesman says hospitals in the District were busier than normal Tuesday partly because of the frigid weather. Those crowded emergency rooms caused backups in some ambulance services across the city.
