Description Pony Bob had traveled more than a hundred miles. Exhausted, he still kept moving. As a Pony Express rider, he had mail to deliver. Suddenly, he heard yelling. A group of Paiute warriors were chasing him! Bullets whizzed past him. One bullet struck his shoulder; another grazed his cheek. But Pony Bob never stopped until he reached his destination. Although the Pony Express Company didn't last long, their young riders left behind a legacy of bravery. Traveling on horseback, the Pony Express brought mail from Missouri to California.
