Beautiful, just beautiful. Stunning part of the world.
Here's what brought me looking for this thread:
The street artist Banksy has been busy bringing his particular vision of the Olympics to London. He's posted pics of his latest efforts, without naming their locations. It is to be hoped that those currently organising the graffitti cleanups will recognise a Banksy when they see it and not clean it away!
