Swimming lazily about in this water are some rather large Koi Carp, just a bit larger than those goldfish you took home in a polythene bag from the fairground. They seemed to swim around the perimeter, one lot going one way and another going the other. I was fascinated at the way they dealt with chance meetings with one another. They passed above and below and it certainly seemed as if there was a 'waterway code'.

In estate agents' speak this would be 'Ideal for a growing family'!
