Prince of the Subway.

Some time needs to be spent discussing Nate's obsession with trains. I'm not talking about Thomas the Tank Engine, or Lionel, or Brio, or "The little engine that could." For Nate, it's the NYC Subway system, period.
Nate has as comprehensive a knowledge of the subway system as I do--which isn't saying much--but it's pretty damn good for a 2.5 year-old. Nate knows the color of nearly every train symbol in the system and can tell you multiple ways of getting to Brooklyn, and Queens from our house. His favorite of course is the number 1 since it's our local train.
