It is late summer and I stand at the edge of the escarpment above anarrow valley called Scarth Nick, in the Cleveland Hills of NorthYorkshire, in the north of England. The weather is bright and sunny with a little haze and the purple bloom of heather on the moorland behind me is just fading. This scene used to be my home, for I was brought up on the farm that lies on the scarp slope below me. However, it is some 30 years since I lived here. My infrequent visits have allowed me to see the changes more clearly, whilst I have widened my experience of life and landscape during my extensive travel and work around the world. What once I saw with the eye of an active participant, I now see as a passive observer.
