When I was recently back in the US, my family and I went to Penn National racetrack to watch ostrich and camel racing. As you can see in the below videos, the ostrich race was the more entertaining of the two. Actual jockeys rode the ostriches and had to do everything that they could to stay on. After the race, one of the ostriches jumped over the track fence and was on the loose. People on horseback frantically raced after the ostrich as it headed towards the nearby highway.
