I went to Windsor on a work trip. Work kept me pretty busy, but I did find time to see the Windor Castle. The Queen was there, but I didn't see her. It was an amazing castle. Another cool thing I did was boat dinner. The boat went through a lock that was only 8 inches wider than the boat I was on. It was a tight squeeze. The work aspect of this trip also went very good, but I can't really discuss that.
Here is a link to a bunch more photos from the trip.
