Huge Pylons

Stig

Just crossing the river at Dartford and noticed two huge electric pylons just down river. I don't know how many hundreds of times I've crossed that bridge and never noticed them before. How long have they been there?

Wow, nearly as old as me then. Wonder what else I've missed all these years.

We used to have huge pylons at breaktime in the Geography room.
