It may only be in San Francisco that when something is in need of replacement, politics gets in the way.
The Castro's historic rainbow flags are 10 years old and normally would be replaced with new, shinier, rainbowier flags but the poles that hold the flags are designated historic landmarks.
The designation makes it difficult to fly something permanent from the poles because they are protected from any potential damage.
