If your from the hood, I'm sure the sight of sneakers hanging from power lines is no unfimiliar sight. So I thought it would be interesting to do some research on the subject.
"A number of explanations have been proposed as to why this is done. Some say that shoes hanging from the wires advertise a local crack house where crack cocaine is used and sold (in which case the shoes are sometimes referred to as "Crack Tennies"). It can also relate to a place where Heroin is sold to symbolize the fact that once you take Heroin you can never leave a reference to the addictive nature of the drug.
Others claim that the shoes so thrown commemorate a gang-related murder, or the death of a gang member, or as a way of marking gang turf. A newsletter from the mayor of Los Angeles, California cites fears of many Los Angeles residents that "these shoes indicate sites at which drugs are sold or worse yet, gang turf," and that city and utility employees had launched a program to remove the shoes. These explanations have the ring of urban legend to them, especially since the practice also occurs along relatively remote stretches of rural highways that are unlikely scenes for gang murders or crack houses.
Other, less sinister explanations also have been ventured. Some claim that shoes are flung to commemorate the end of a school year, or a forthcoming marriage as part of a rite of passage. In Scotland, it has been said that when a young man has lost his virginity he tosses his shoes over telephone wires to announce this to his peers. It has been suggested that the custom may have originated with members of the military, who are said to have thrown military boots, often painted orange or some other conspicuous color, at overhead wires as a part of a rite of passage upon completing basic training or on leaving the service

Others claim that the shoes are stolen from other people and tossed over the wires as a sort of bullying, or as a practical joke played on drunkards. Others simply say that shoe flinging is a way to get rid of shoes that are no longer wanted, are uncomfortable, or don't fit. It may also be another manifestation of the human instinct to leave their mark on, and decorate, their surroundings". -Wikipedia.com
