On our P-Day last week we decided to take a tour of the famous Metro system of Moscow. After I got over the initial shock of going deep, deep down into the metro we had a wonderful time exploring the beautiful metro stations. To give you an idea of how deep some of these stations are, many were used as bomb shelters during WWII. Most of the metro lines are like spokes that meet at a hub in the center. The Brown Line is an exception and is a circle that crosses all the other lines. Many of the stations on the Brown Line look like art museums. Also, they are so clean! We didn't see any trash at all, not even a trash can. They say 9 million people ride the metro system every day. Wow!
