I'm not sure how long I'll be able to keep this up, but for now I'm trying to avoid trips that require getting on an airplane. Which means that if I do want to travel abroad, I look for places just across the border. So when I received an invite to visit Essen and Duisburg in the Ruhr Region in Germany, I couldn't say no. The Ruhr Area is probably not the first thing that comes to mind when you're planning a city trip to Germany. But it's really worth it. What makes it especially interesting is that there are many places to visit only a short distance away from each other. Essen to Duisburg is only a twenty minute drive. And also cities like Cologne, Dortmund...
