Where am I?

There is an attempt to modernise the image of the London Tourist Board, captured in a new advertising campaign. In a departure from the traditional shots of Beefeaters, Changing of the Guard and punks with mohican hairstyles, it uses the distinct U-bend shape of the river Thames as a visual leitmotif in a variety of settings, and carries just two words: visit London.

Yesterday I saw one of these ads on a train on the London Underground. I am not sure exactly how attention-deficient the average visitor to London is, but if people do find that particular ad useful or well-placed, I'd wonder how on earth they managed to tie their own laces, never mind negotiate the interchanges on the Central Line.
