Um actually I'm American :3 I grew up in Kansas but my husband is French. We met on Gaia Online back in late 2004, early 2005. And then in Aug. 07 we got married I and moved over here for good!

And the zones are how they split up the city. This is a link of the subway maps and there are tan and terracotta colored circles around it. Well Paris is 1 & 2 and then 3 starts to go into the more suburban areas but really it's just wall to wall city even into zone 4.
