With the big day getting closer, Prince William and Kate Middleton went to Westminster Abbey for a final wedding rehearsal on Wednesday. They were accompanied by Prince Harry and Kate’s parents. The couple worked with the Abbey’s senior clergy to work through any last-minute issues in the ceremony. (When 2 billion people are expected to watch your ceremony, it’s important to work out all the kinks.) This morning there was a full run-through of the military procession outside, which featured a Kate look-alike as a stand-in. Meanwhile, fans have already started gathering around the church to claim a spot for the big day. However, not everyone around the Abbey is excited. Homeless protesters are refusing to leave the area, and bomb-sniffing dogs are on patrol outside the Abbey.
