Funny you should mention the Thames Crossing pylons, I did a search for Kent pylons to see what might come up as a potential day out and those are the biggest in the UK.
Now just to be clear, I’m not thinking about going on a trip just to see pylons, pylons would just be one of several things we might go to see on such a day trip.
I can really appreciate the geometric shapes & compositions (for instance found in that video I posted, particularly around 4:00 ~ 5:00 minutes in) but that’s just one side of the coin, they’re still fugly too.
