What is it about a pylon that attracts people with cameras? Is it the intricate patterns formed by the tower and high-voltage cables? Or is it the silhouettes that form in front of the sun? There is even a Pylon Appreciation Society.
As for me, I like the stringed glass insulators light up from from behind by the sun, as seen in this picture.
