It's time for TravelGumbo's weekly photo puzzle! Last week's winner, Port Moresby, got the answer so quickly, we've made this week's a bit harder.
Submit your answer as a comment to this blog as soon as you can: There's no prize but the glory of being first with the right answer.
And next Tuesday, we'll post the answer, with more info and travel tips on how to enjoy a trip to...well, to this place!
