The Golden Fire Hydrant
"Though the water mains were broken and dry on April 18, 1906 yet from this Greenberg hydrant on the following night there came a stream of water allowing the firemen to save the Mission District.
Dedicated to chief Dennis Sullivan and the men who fought the Great Fire and to the spirit of the people of San Francisco who regardless of their losses brought our city from its ruins to be host of the world with their 1925 Pan Pacific Exposition and the building of our Civic Center.
May their love and devotion for this city be an inspiration for all to follow and their motto 'The city that knows how' a light to lead all future generations."
