Eileen sent me a great metro map card from Paris!
The Paris Métro or Métropolitain is the rapid transit metro system in Paris, France. It has become a symbol of the city, noted for its density within the city limits and its uniform architecture influenced by Art Nouveau. The network's sixteen lines are mostly underground and run to 214 km in length. There are 301 stations (384 stops), of which 62 facilitate transfer to another line. Paris has one of the densest metro networks in the world, with 245 stations within 86.9 km2 of the city of Paris. (source)
