Slightly OT - I play a similar game on Facebook with a very good cycling friend. We both know the roads of Devon, the local scenes, and each other's riding habits fairly well, so we can get pretty sneaky. I think the best one was when I posted a picture of clouds reflected in still water. All my other friends thought I was being silly, but my clue of "still waters" gave my friend the hint 'run deep', he worked out that it must be a reservoir, and his first guess as to which reservoir I was most likely to go to was correct.
