Florence, Alabama has a local legend that a prostitute plied her trade on the south side near Wilson Dam while riding a bicycle built for two, and carrying her customers to her apartment nearby. Unfortunately, I have not found any concrete evidence of this very enterprising working girl.
However, there is a lot of circumstantial evidence that a Kate Nelson was a madam who operated a disorderly house in South Florence during the 1920's. It was especially popular with construction workers who were then building Wilson Dam. No locals owned up to visiting her, and it's likely that this sort of history is not appreciated by the local Fundies!
