Well, I may have just accidentally invented a new Fox game. My printer ran out of cyan ink, leavimg my map rather yellow. Not being able to distinguish open from dense woodland was interesting and led to one big mistake.
Plus I missed the finish, not noticing on the ground what seemed an obvious kink in the hedgeline on the map before the finish and thus ending up turning up a hill within 3m of the finish. The lack of visible woodland on my map didn’t help either! Oh, if only there’d been a flag or a kite, or even an SI box on a stick! Lost several minutes there.
