Sometimes the most interesting discoveries happen when you remember to look up!
One thing that has really impressed me about Prague is how clean and well-maintained the public transportation seems to be. I've used the subways and buses in New York City, so I have something to compare them to. While Prague's trams, trains and buses aren't necessarily brand new, they seem to be well cared-for. I've noticed that the service vehicles are generally clean, and the transportation system has made getting around the city a pleasant experience. It's interesting to see how two major cities can offer similar types of public transportation but provide different experiences for passengers. Sometimes the most impressive thing isn't having the newest equipment. It's how well you take care of what you already have!
