As a child I used to often see shoes hanging from telephone and electric wires. I haven’t seen that in a long time. (Still living in the same city.) Happened to see it again today and remembered about them.
In my town, I heard they’re meant to indicate drug dealer’s place of residence or sale. But I assume Reb Yidd must be correct, because if I heard about it then I’m sure the police have heard about it way before me. So though they may have been used for drugs at one point, I think they’re a form of modern urban art now.
most people dont know this but since i unfortunately know people either on drugs or once were they said it means theirs drug selling going on somewhere near there.
