Traveling is fun. I especially enjoy traveling by train in Europe. The trains are very efficient and clean and are a super way to get around in most any country (or between countries, for that matter).
I'm particular fond of the ICE trains in Germany. They're terribly sleek and very comfortable. There's nothing quite like zipping along at 175 miles per hour while you watch the landscape melt by, though it's particularly nice to do so from the dining car while having a little soup and a cold Apfelschoerle.
