1. Shoes on wires
There are several opinions concerning the appearance of this phenomenon:
- This is a way students celebrate graduation, and military men the end of service, by throwing up in the air everything they have at hand.

- Tossed shoes show the limits of the zone of influence, informing people that local "rules" change beyond the power lines.
- In New York and Los Angeles, these are secret signs of local criminal groups’ members to each other: the neighboring house sells drugs. The color and shape of the shoe determine what you can buy.
- Shoes are thrown at wires by thieves to create a power surge. While workers are dealing with it, the thieves steal the wires.
