Scurry Driving at the Herts Game Fair

I'm the first to admit that I don't know a great deal about equestrian sports. Show Jumping and Racing (does that even count?) are probably the only two disciplines that I could name that involve people riding horses competitively. So when I went along to the local game fair & country show I was quite interested to see people riding around very fast on small carriages pulled by pairs of ponies. It's a sport called Scurry Driving and it's quite exciting to watch.
