Until moving here, I had never seen shoes tied and hung from electric lines before. Where I grew up, electric, telephone, and television cables were maintained underground.
It wasn't until today, prompted by taking this picture, that I finally remembered to look up "shoes power lines" and discovered the term for this activity: shoe tossing or shoe flinging.
Reasons apparently vary from a man celebrating losing his virginity to signifying a crack house, graduating from school to mourning the dead (deceased's shoes are flung).
Aside from mourning the dead, someone out there is missing a pair of shoes. Hopefully it didn't occur in the dead of winter unexpectedly.
