Other top searches are pretty practical, like "How do you get to JFK on the subway?" and "How do I ride the NYC subway?" -- the latter of which, despite the ranking, is probably not asked often enough. Oh, and if you're taking the time to Google the No. 6 question, "How do you meet women on the subway?" then you should probably just avoid the trains altogether.
Here's the top five:
1. Is the L train running?
2. Is the MTA working today?
3. How do I get to Yankee stadium?
4. How do I ride the NYC subway?
5. What time is the MTA shutting down today?
