Schwartzmoor, thank you for gifting us with soem a fine present.
The sight of St. Basil's in Moscow reconfirms Moscow as a stop. Oporto is a surpise, but it is the second city of Portugal(with the great port wine produced in the region around it). The gaps that remain are between Salvador and Bolivia and between Dubai and Moscow. I did not recognize anything that helps show what those places are.
I saw no pictures of Iguassu Falls, so if this photo album is a retrospective of where AR13 went it apparently did not go there. Also, I saw no photos of Dubai itself, so it apparently did not leave the airport there. Also, there are no pictures of Frankfurt, so I conclude that teams did not venture beyong the Frankfurt airport after arriving from Oporto.
