As one expects from Cities, San Francisco offers its fair share of contrasts - oversized humans in funky pants and handbags, a Japanese couple stretching stiff granny muscles with Ti Chi movements, drug-sleeping lovers in a park, my friend Melanie and panting up endless stairs to be rewarded with views not only of more skyscrapers but romantic Victorian homes, in an area that forbids new architecture. Breathtaking lighting frame skyscrapers after dark.
