Just put in any two addresses (anywhere including NYC, NJ, Westchester, and Long Island) and Hopstop will tell you how to get there by subway, bus, or walking. You can even look up cab fare!
If Hopstop makes you feel too cliche try Google maps and put in public transit or walking (or both if you live on the edge).
Or if you don’t trust outside sources (unlikely if you’re on this website with a semi-real domain name) try the official MTA site.
