Tip: Get the fun passes (they're like $4-5.00 something like that)....unlimited rides on MTA subways and buses for an entire day (after like the 4 fare you've already made up the difference in cost as if you were to pay for 4 seperate fares).....buy 'em at subway stations.
I may live in FL but I'm a New Yawker
