We saw Christ Church, where some scenes of Harry Potter were filmed. No flash allowed, though.
From Oxford we went and had lunch at a lovely little place in the Cotswolds, on our way to the main event: Stratford-upon-Avon. We saw Anne Hathaway's cottage and Shakespeare's birthplace.
Some of it was very tourist-y, of course, and I remember a moment when I was looking at some of the artifacts that were dug up and the labels slapped on them and thought "Seriously?" But at the same time it was fun and interesting to see such history. Before we left, an actor in the garden was performing Marc Anthony's speech from Anthony and Cleopatra.
Then back to the hotel, and back home to America. All in all, I consider it a very successful first trip to Europe for me. I had a great time, I saw a lot of cool stuff, I took some pretty pictures, and I met some wonderful new friends.
