Triptrop NYC: Completely Rad Subway Time Maps
Plug in an address in New York City, and Triptrop generates a super slick looking map of how long it takes to get everywhere on the subway. And maybe you're moving?
Then plug not one but two
addresses into the address comparison version
and see which one gets you where you want to go! Oh, joy.
