In this tale, the Thompson Brothers turn their Eldorado Ranch into a beautiful race track so the Cousins can enjoy racing their pet horses. Chris's horse "White Lightning" becomes somewhat of a super star when he beats Secretariat's racing record. When the Mayor and Racing Commissioner of San Angelo, Texas, learns how fast White Lightning can run, they suggest he be entered into the Kentucky Derby, Preakness and Belmont Stakes, believing he may be the next Triple Crown Winner. However, there is a slight problem. What problem is that you ask? You will have to read this delightful and humorous tale 'A Day At The Races' to find out.
