Racegoers on an open top bus during Investec Ladies' Day of the Investec Derby Festival at Epsom Racecourse, Epson, southern England Friday June 1, 2012. Queen Elizabeth II kicks off a long weekend of celebrations of her 60-year reign by going to the races, and perhaps no other event will give her so much pleasure. The Epsom Derby is the richest event on Britain's horse-racing calendar, and never mind that this is the only major race in which the queen has never entered a winner. Pleasure, in the gilded life of Queen Elizabeth II, often comes on four hooves. (AP Photo/Dominic Lipinski/PA Wire) UNITED KINGDOM OUT less
