Click on the picture to blow this up. It's one of the reasons our trains are so amazing. (Hint: it expresses the sentiment I think of when I see the accomplishments men have achieved since the start of the last century).
I love walking through here. 20 years of marching around this station and I still can't get enough. I know I haven't seen the entire place.
I am definitely getting to Grand Central the next time the trains go up (in November 06) with a camera!
