The Oceanside Pier has stood for 135 years in San Diego county, California. On Thursday, first responders were called to put out a fire on the local institution. The fire started just after 3 p.m. at the end of the historic pier. Helicopters dumped water from the skies while boats fought the flames from underneath. The exact cause of the fire on the nearly 2,000-foot-long pier is under investigation, though officials believe it may have started in a vacant restaurant.
