Officials are Charlie Boyd of KY and associate judge Joe Myers of KY. • Two days before the start of the stock show, a group of steers are paraded through the streets of downtown Denver, which is quite a sight amid the city's skyscrapers and coffee shops and a sure sign the city has gone stock-show crazy.
