In 2004, Congress designated December 13th as National Day of the Horse, to recognize the contribution of horses to the economy, history, and character of the United States.
That same year, they amended the WHB Act to allow sale without limitation of wild horses and burros more than 10 years old or those that have been offered unsuccessfully for adoption at least three times, a change that further weakened the protections of these animals, to the benefit of the public-lands ranchers.
