Where to go...

So I was looking through a friends facebook pictures today. He is currently studying abroad for a year in Germany as part of the international engineering major. He recently put up some pictures from Berlin and it looked like a really great place. I was thinking about the History and how great it would be to see the Berlin wall. Now a days there is a ton of art work decorating the wall. I would love to see that. I will have to add that to my long list of things to see before I die. I find it so fascinating to visit place with such unique history. It sounds like a beginning to a story.
