John, I don't know if it is an urban legend, but I remember hearing years ago, that shoes thrown over electric/ phone lines is a sign for those looking to buy/ sell drugs. I don't know if it is true or not, or if as you said, it's just people being stupid.
Someday I will manage to go to Mecca.
Someday.
Until then I will need to live vicariously through those that do go. So keep posting your thoughts and photos please ~Jan
