Cool subway, bus and train maps can be found at http://www.lirr.org/nyct/maps/index.html

Click on subway maps and so on. Makes nice wallpaper!

Well, have fun on your ride in. (If you take a taxi, there was a highly amusing post by IDUR a little while back. I guess IDUR is RUDI backward. It always makes me laugh, and it is good to keep your sense of humor when traveling in NY!)
