SAN FRANCISCO (AP) — Red lanterns sway in the wind. Streetlamps from the 1930s cast a yellow-green glare onto century-old buildings. Neon glows from a pair of dive bars. Figures are silhouetted waiting outside a restaurant, and a lone woman makes dragon beard candy in a tiny storefront window. All are nighttime scenes along Grant Avenue in San Francisco's Chinatown. The avenue, which runs north and south, is one of the oldest streets in the city.
