The geography of the street hookers' strip is outlined in terms of the places of sex trade and drug trafficking. Enforcement policies, intended to discourage hard drug scenes, have consisted of intensified uniformed surveillance and arrests directed against petty thieves and drug dealers. While some addicted street prostitutes have moved to other locales and addicts and dealers can no longer frequent certain areas, a hard core of 400 addicts and street prostitutes has remained in the area. The article focuses on the chronology and personnel of the German Bridge, in particular noting the interactions of the prostitutes' social isolation, tourism, and drug use. While condoms and clean needles are distributed freely in this district, the incidence of AIDS among intravenous drug abusing prostitutes remains quite high. 1 figure and 6 references
