Sneakers on power lines

There's a pair of sneakers hanging over the power lines on North Shore Road near Store Hill. Been there for quite a while, actually. I don't know what the safety hazards are for this (like, could a large truck catch the sneakers and yank the line down, for example?), I suppose Belco will deal with it eventually.

Why would somebody tie up a pair of sneakers and hoist them over the power lines, though? Apparently another thing we've copied from our American friends, I searched online for possibilities.

They range from the clowning-around variety:

• bullies take them off defenceless kids, then sling them up out of reach as the ultimate taunt
• overly puffed-up boys who have just lost their virginity or otherwise passed a sexual milestone look to signal the event to others
• graduating seniors mark this transition in their lives by leaving something of themselves behind; namely, their shoes

to the more serious and or possibly dangerous possibilities:

• the work of gangs marking the boundaries of their territory (in Bermuda, I don't see that happening, just because the gangs seem to already know each others' "territory")
• a location where one can buy street drugs (I wouldn't doubt this, but it seems like a lot of overkill; besides, why tip the cops off?)
• creating an informal memorial at the spot where a friend lost his life (possible, but the Bermudian tradition is just to spray paint the roads with messages and hang up bedsheets with messages written across them, so that's maybe a little doubtful)

What do you think?
