From "A Municipal Report" by O'Henry

East is East, and West is San Francisco, according to Californians.
Californians are a race of people; they are not merely inhabitants of a
State. They are the Southerners of the West. Now, Chicagoans are no less
loyal to their city; but when you ask them why, they stammer and speak
of lake fish and the new Odd Fellows Building. But Californians go into
detail.
