This is a good idea, but I think most people don't have the patience of ranski to nanny the thread while everyone is making wild guesses. I suggest a DIY game where we can check our own guess against the slightly hidden right answer. Easy to cheat, and you only get one guess, but we should get more challenges submitted, as anyone can submit, not just the first winner.
I suggest that submissions place more emphasis on interesting photos of your Zed in interesting places, even if it is a well known location, rather than obscure, uninteresting but challenging locations. The idea being it would be fun to look at the pictures, even if you were not interested in playing along. Finally, we should restart this thread in the gallery section, just makes more sense.
How to hide the answer? I don't know how well this will work, but if we format the answer text with color=#EFEFEF, it should match the background of the post and be essentially invisible, as long as you are not overriding the site's CSS. To see the text, simply select it. This should work until the site restyles their background colour.
So here's my example challenge, mainly to see how my idea works, don't really expect anyone to recognise the location, but the pic is sort of interesting. See you in the Gallery Section.
Clue: The location describes the scene.
