Heading north, pass where you used to turn in to his house / old place.
after about 1/2 a mile, opposite the road that goes down to the RAF place, on the left there is a small road. Has a sign post to some old folks home.
Follow that road, and after the 90- degree right, there is a smaller road that goes over a bridge, take it and follow road.
Guess about here :- http://www.multimap.com/map/browse.cgi?lat...ale=5000&icon=x
