I don't see what the problem is. Fellow down the street from me when I lived in South Clinton ran his own escort service. Had a pickup truck with flashing lights and signs that said "Wide Load" or "Slow Traffic" on them. Made a pretty good living following those tractor trailers around.
Oh they have those everywhere in the South, especially where I hunt.
Seriously, everytime I go hunting, on the way to or from, I will always get stuck behind one of the "RV Campers". And you know it's a prostitution wagon, cause they use a certain kind of trailer.
