Day out - camera comment

I really want my blips to be about outdoors in the countryside, natural landscapes and wildlife, but I've had a few days when this has been impossible. Today I was in London visiting museums and at the Proms at the Royal Albert Hall. I was resigned to not getting a photo I'd be pleased with, but later I found this one that was taken by accident - it sort of summed the day up and I concluded it was a comment from my camera.
