We have received abundant submissions to our puzzle challenge.Our thanks to all of you that made a guess - many of you even submitted the correct answer! We'll try to reply directly in the next week or so. We've enjoyed your comments.At this point, it looks like we have two or three confirmed winners: Europe (Sweden), South America (Brazil), and maybe North America.Since we still have other continents that can win the challenge, we aren't going to reveal the answer yet. We'll save that for a future post. Cheers.
