Game & Event Hosts

I have an idea for a side game… Ill Pitch to you to see what you think. I was thinking of going to a random locale, off the beaten path, taking a small pic with only a bit of the locale showing, and posting it on the news feed page, and whoever can

correctly identify the EXACT name of the locale, would win a few vouchers? or some type of prize? Its like a hunt, without hunting. Maybe get people moving around to find where that locale might be to get the exact name?

also while gaining some more interest/focus towards the new feed page also. Going there to check the for posts is the only way you can win. I can do this like 2x a week, randomly, different times
