Nothing particularly eventful occurred in London, at least, nothing seems to come to mind at the moment.
It's worth noting that I managed to get Magic cards in every country I visited.
Pictures should appear soon.
I was present at midnight for the release of Harry Potter and I read it all on the day-long plane rides back home. I must say, J.K. Rowling needs a better editor, since the book could have been significantly better if it wasn't a great beginning and ending wrapped around approximately 400 pages of dull exposition and uninteresting goings-on at school. Basically, the book is like an Oreo with really boring filling.
p.s. Snape kills Dumbledore! Spoilers!
