I have never been good with directions, and the City gets me particularly turned around. Well,goddamn, I made it from the Upper West Side all the way to Jamie's apartment in BK all by myself thanks to the Embark NYC (FREE) application. This app is priceless. You type in your starting address and your destination, it finds the closest subway station and then gives you multiple routes and how long they should take (approximately). Love love love this app.
