There’s one cacher in this region that logs as a find but says can’t remember when they found it. As it happens I once replaced the log of one they had claimed and after I’d dried the old one out I couldn’t see their name anywhere. Nothing to say they hadn’t done it, perhaps in a far-previous logsheet (at least a year in that case!), but seems a strange way to play the game. No skin off my nose though, if they want to do it that way!
