By "open cities" in the mafia world means that any Mafia family could operate there without permission.Its like vacation time for mobsters in cities like Miami,south Florida,mobsters used to visit there since the 20's,from Capone to Scarfo.In the 1990s authorities estimated that over 600 members from diferent crime families in America were in South Florida.
San Diego, California,Des Moines, Iowa were open cities too.In Youngstown, Ohio there was a lot of gambling operations so at some time it wasnt an "open" town anymore cuz there was a beef between the Cleveland and Pittsburgh crime families.
My question is...are some of these cities still "open" for the mob today?
