So even just looking at the name of the station you know this is another hard one... it spans 4 blocks right off the bat! Although, the reason this is a tricky one has more to do with the fact that it's a combination of a large complex that is the Rockefeller Center and the subway station itself. It's hard to draw the line between which is part of the station and which isn't, since there are a few spots underground where the station mezzanine connects directly to the buildings above ground, and some of them connect to concourses. I'll take more pictures next time!
