Stop press. Oh dear. Just as I was posting the instalment below comes breaking news of an explosion on the Yale University campus. It's not clear yet whether it's terrorism (international or Unabomber copycat), a disgruntled grad student, or a gas main, but it's not good. With the country officially back up to orange alert, suddenly it doesn't feel so great to live close to a big-name university, nor to be moving to one that has just had an explosion at it...
