I did however take a number of shots and one of those is my representation of 'Evidence of action'.

The 'Evidence' is obviously the ploughed strip and kinda like that it is actually not the most dominant part of the image. Attention is drawn to the strip by the judges who are looking at it. The other end of the strip is blocked off by the horses, which stop the eye from following the furrow and then leaving the frame.
As a little self critique, I do wish I had angled the camera to allow just a little more of the ploughed area. Perhaps if I had moved a couple more feet to the left so that the furrow was angled like in the picture below?
