Beautiful old city on the Rhine. Cologne Catherdral was huge, and was the tallest building in the world for a short period in the 1800's, at 157m tall. You can walk up 20,000,000,000 steps to reach the top for a great view of the city. McDonlds there is packed with annoying californian girls, but they serve up a mean chips with mayo. Museum of German and Roman history is a nice collection, but deathly boring.
