Have you seen these guys?

Alright, folks!

..Sorry for staying quiet (or blind) for a while. But here's new pictures. Taken in December.

Does anyone know who these guys are? 

I've heard that one of them is from France, second from Italy and third is from Spain. And that they were traveling to Budapest, Hungary, from Bucharest, Romania, with one guy from Finland. 

Nevertheless, I really haven't seen them since (as the same group).

Ps. The 2nd last photo won the Erasmus photo contest on FB, with pictures that best describes each's Erasmus experience. My experience: "A jump to unknown."

Thanks again for all likers!
