For those complaining about rail, I suspect, among other things, that any Metro-North expansion into Rockland: (i) isn't economically justifiable since the total commuters from Rockland is probably pretty small; and (ii) it would probably be cheaper for any rail extension to travel on the west side of the river and cross into Manhattan from NJ. The location of the Tappan Zee/Cuomo Bridge is one of the widest points of the Hudson.

Anyway, lots of Rocklanders who choose to take mass transit drive into Tarrytown and take the Hudson Line from there, or they go to Nanuet, which I believe lets them off at Seacaucus or Penn Stn.
