The celebrations have ended, the final medal count is in, and the mass exodus has begun.  The sun has set on the Games of the XXX Olympiad, completing one more chapter in athletic history and leaving the world with a fresh batch of indelible memories.  While Her Majesty did not attend the Closing Ceremony, instead we got the Spice Girls, Eric Idle and a giant octopus.  Two amazing weeks have ceremoniously come and gone, and now amid post-Olympic pride and glory London can get “back to normal,” whatever this might mean.
