Royal Wedding Countdown

The excitement in and around London is electric as locals and tourists alike gather near that city's iconic landmarks, all in anticipation of Friday's royal wedding.

Five thousand police officers will be on patrol, as well as, nearly 250 horses and 35 sniffer dogs.  They will scour everything from the inside of the Abbey to sewers and lamp posts looking for anything suspicious.

An estimated 600,000 tourists are expected in London this week, many of them from the U-S.  Tourism experts say the number of Americans visiting London is up 20 percent this month.

You can watch ABC's special live coverage of the events leading up to Friday's on KTRE, as well as, in-depth coverage of the Royal Wedding beginning at 4 a.m. (eastern).  An estimated two billion people could watch on the big day.
