Golden Slipper Race Day Protest

The Golden Slipper is the world's richest race for 2-year-old horses. $5 million in price money are at stake and the far too young horses are risking their lives for it.
Racing is the only horse 'sport' in the world allowing underdeveloped 2-year-old horses to compete - or even just carry a rider. Rather convenient for the racing industry as they wouldn't want to be feeding a horse for an extra couple of years before making a profit from him/her.
