Ok, more about Moscow and what I am doing there.  Moscow is a huge city of 16 million people.  The center of the city is connected by the metro.  The metro is very convenient to get around on, but unfortunately, I live in a small town on the outskirts of the city where the metro does not reach.  So, I take a train to get to the metro, and then I can get around the city.  I enjoy the public transportation.
