Polk Street Transformed

"For years, Polk Gulch was one of the most notorious neighborhoods in San Francisco, home to drug addicts, prostitutes and some of the city's seediest nightlife. But it was also an early mecca for the city's gay community -- years before the Castro District. Over the last decade, neighborhood groups have been trying to cut crime and drug use in the area and attract a new clientèle composed of the young and well-to-do. But in the process, some say, they are erasing the last remnants of the neighborhood's LGBT past."
