There is a permissive attitude toward prostitution across the border from Laredo, Texas, in "La Zona" ("The Zone") in Neuvo Laredo, in Mexico. That area of Nuevo Laredo is also referred to as "Boys Town." There was a history of these sort of "Boys Towns" along the Mexican border dating back to US soldiers pursuing the paramilitary forces of Pancho Villa in the early part of the 20th century.
