You know the nursery rhyme about "all the king's horses." well, in Britain yesterday, it was the Queen's turn! It happened on a very traditional and colorful racing day known as Royal Ascot. It's an annual week of horse racing outside London. The Queen entered her own horse in this race. She wore lilac, to match her horse, Estimate's, racing colors. She became the first reigning monarch to win the Gold Cup in it's 207 year history.
