Did Detroit have other prostitution-areas before the current ones took hold, and when did the current places start to get popular? For example, John R between 8 Mile and 6 Mile; Harper around the old Holiday Inn that's now the Travel Inn; the Triangle; etc. Is 1 area considered "better" or "safer" than another? Someone has posted on another board that a couple of regulars on John R around Lantz were, at one-time popular "models", 1 for a Budweiser calendar, the other a Georgia-based teen model with a popular website around 2001-02.
