San Francisco is its own country with liberal values, handsomely manifested through visual cues scattered in all neighborhoods. Richly playful architectural elements and surprising colors bombard the saunterer with playful freshness. As one takes a closer look at the doors and windows, more unexpected elements pop up: buzzers are cocky, even avant-garde; door numbers in all possible colors and materials are crafted with leisurely bravery only a San Franciscan can afford.
