Niall,
If I make it, and the if seems required as I've tentatively planned this trip for the past two years but circumstances have intervened, I intend to play the Machrie two or three times. That should provide ample opportunity to take some photographs. At this remove, 125 years, any evidence of what might have been on the ground could be difficult to detect.
Oddly, the 800 yard number seems to resonate with me and I know I expected to see a greater length than 750 yards when I went to the Campbell book.
Which hole is the Spion Kop, or are they identified on the card? I don't think I've managed to encounter one of the numerous Spion Kops that are scattered through the courses of GB.
Speaking of dodgy memories, I can't find any indication that the Malcolm Campbell I met in 2000 is a knight, but I swear he was introduced to me as such or identified as Sir Malcolm Campbell prior to the meeting. Perhaps someone was having the overseas visitor on. I should have asked to see his speedboat.
