Just a reminder on how this works: I post the mystery photo on Monday and reveal the answer on Friday ... or on Saturday if I have a hard time picking only five pictures; sometimes it's difficult to choose. To keep the mystery photo from getting lost in the other entries, I move it from Monday to Tuesday to Wednesday, etc., adding a photo every day.
I have to approve all comments, so if your guess is posted immediately, that means you're wrong. (And if a wrong guess has already been submitted by someone else, there's no point in submitting it again).
If you're right, you will have to wait until Friday. There's no need to submit your guess five times. Once is enough. The only reward is bragging rights.
