Susan King returns with a new series about horses and ponies, and the people who ride, drive, jump and breed them.
This week Susan visits Hampshire farmer Tom Sampson to see his antique horse-drawn steam fire-engine in action, looks back at the history of the misunderstood but still popular mule, and finds out about riding as a games option at some of London's largest schools.
