A Police officer friend told me a common sign of shoes/sneakers hanging from the power lines or telephone lines means that there is a drug dealer available in the area. It's a type of advertising ... I guess its subtle and less invasive then the large graffiti tags drug dealers use to paint all over buildings lamp posts and alleyways.
So the shoe thing on the wires has been successful for advertising ..... I wonder, how does one find your local drug dealer when you see shoes hanging on the line? Do you drive or walk around looking for the person who isn't wearing any shoes?
Hmmmm .... inquiring minds need to know.
IN the meantime .... this Mama figured out how to make some advertising work in her way!
