Sunday Morning Sight

Saw an unusual sight while sitting having coffee this morning: among the traffic I noticed a horse tossing it's head, rather wild-eyed, and as this came closer it became apparent that the horse was being trained to be driven in traffic. A man in a trap with huge wheels was behind it. I don't really know what they are called - it's the kind of thing the Duke of Edinburgh drives for sport, I had thought it was a phaeton, but it seems that is a four-wheeled carriage. Oh well.
