We hardly even notice them most of the time, yet they are a decided rhythm to the world we are familiar with.  Power poles are probably a species on the verge of extinction, and not the first thing you'd think of to make-pretty with.  But once you start looking at them, they get fairly addictive, and then there is all that deep meaningful stuff about connections, communication, change. Lots of good metaphors, let alone that they are actual lines of power. And they look kinda cool.
