Traveling in Greece

Well, I am intensely jealous of my son, Benjamin. At age 19, he is traveling with a backpack throughout europe for 2 months. trains, buses and alot of walking. What an experience. I did it myself when I was 20 after my second year in college, now he is off. He's in Rome this week, but started out in Greece. He posted a few photos for us to view. In the photo of the three, he's the one on the left. The guy in the center is some kind of guard in Athens, I'm not sure who the fello on the right is - image must have been taken by someone he met along the way.
