Horses

For me the best in monarchies are the horses. And where do you find the best horses and ponies? The answer is, in England, in Scotland and in Wales.
However,  there can be exceptions. My beautiful (black) Icelandic horse came from Iceland which is a republic, and my beautiful (grey) Shetland stallion was born on my own estate in the republic of Finland. But still, a monarchy is almost a guarantee that there are good horses and good horsemanship. :-)

Extra. There is a street full of like-minded people like me. :-)
