London prepares for once-in-a-generation celebration
Coronation buzz is spreading across London as the city prepares for the once-in-a-generation event.
Tens of thousands of people -- including the 2,000 people attending the coronation service itself -- are expected to stream into the city for the celebration.
For the past several weeks, workers have been seen cleaning Buckingham Palace and other landmarks, building grandstand seating areas for viewers and hanging flags across the city. In the darkness early Wednesday, coronation participants held a full-dress rehearsal for the big day.

Security is also tight all around London as officials brace for expected anti-monarchy protests.
