When you reach Alloa, head for the Kincardine Bridge, when you come to the Mary Wood Roundabout with the silver man and woman monument - stupid thing that it is - turn into Clackmannan. Turn right at the first junction, just past a white pub on your right, go up a hill, then turn left at the top into Main Street. Go down almost to the bottom and on the left is the Post Office. Jim will tell you where to go from there as all I can see on the map is a farm in the middle of nowhere. I looked on Bing Maps (google that) and put in the postcode.
