HopStop: New York Subway Guide

Although this topic has nothing to do with Personal Finances, I thought it good to mention a wonderful site for New York City straphangers: HopStop.

HopStop allows you to enter in a starting and ending address (like MapQuest), but instead of giving you driving directions, HopStop gives you either subway or bus directions.  For example, it will tell you to take the E train and switch to the 7 train to go from the Upper West Side to Grand Central.  Total travel time, route changes, and maps are all given.  You can also choose between more walking vs. more transfers.  

If you live or work in New York City, HopStop is an invaluable tool.
