I like to think the subway map in my head is pretty reliable, but the next time I’m traveling an unfamiliar route, I’m going to check out one of the awesomely convenient sites mentioned in this New York Times article.

HopStop (which a mysterious “guest blogger” wrote about last February),
Trips123, and Public Routes all tell you how to get from one New York City address to another using public transit.

As a little test, I just asked all three sites for a route from my apartment to an office building in midtown where I have a meeting tomorrow. They all gave me decent directions, but HopStop seemed the easiest to use. (HopStop and Trips123 understood when I typed in an intersection, but Public Routes required the full street address of my destination.)
