A little while after logging the DNF the CO kindly gets in touch. Two exchanges of messages later and he even more kindly (unprompted) sends me a spoiler image. Now that looks familiar and I'm thinking that I definitely searched that or something very like it. Anyway, with the chores all done I have enough time to give it another look, even if I do have to endure the ghastly rush hour traffic through Dorking. Back at GZ I soon locate that which in the image and confirm it is somewhere I searched before. I search it again, carefully. Nothing. Can it have gone missing already? OK, once more with feeling! A meticulous, ungloved, fingertip search finally reveals the little beastie!
I consider the hint. Yes, it's accurate, though possible less helpful than it might me. Next I take my own averaged reading (Garmin Oregon 650t) and get N51 11.470 W000 20,528, which differs from the CO's by a mere 0.001 in the Northing! However, I know that both my GPS and lamoutarde's were all over the place this morning, so I guess the tree cover is affecting accuracy. No matter, I have it and I'm a happy bunny.
