Last summer, Katie and I traveled to Berlin, where she lived for two years. Katie was a great tour guide, taking me to her old haunts and to the city's many parks and tourism attractions. I had a great time getting to know this world-class city for two full weeks. Many thanks to Maor, Christina and Liese for hosting us. I hope to see you again in the next few years.

Here are a few of my pictures from our trip:
