I visited Berlin in July, 2011, in order to familiarize myself with the city. In June, 2012, I will be teaching a photography course there. Berlin is a wounded city, still recovering from the devestation of WWII. But, there is a quirkiness to Berlin -- a quirkiness that is appealing to artists. Berlin's walls are covered with grafitti. Is it art or just radical mischief? Some of the grafitti is beautiful, and some of it is thought-provoking -- but always memorable.
