Spinnaker towel

Had a long journey from Manchester to Isle of Wight today, made longer by the Island line breaking down. Helpful man on the platform advised walking to the next station, which I did and still had to wait an hour for the train to arrive.
Took this shot on the way through Portsmouth. A friend recently suggested I abseil down it…. I said it was too high and having checked it out close up I still stand by that!
