How to get to Laguardia Airport from Jersey City, NJ?

The fastest way is always by Taxi, but also the most expensive. To get there by Public Transportation, you'll have to first take the PATH train to WTC. From the WTC (world trade center area), take the E train uptown into Queens. Now, for the rest of this, you'll need to have a NYC subway map because there is one stop in Queens (I think it's Roosevelt AVe.) that you can get off and catch a short bus ride to LaGuardia from there. The actual bus number is posted on the subway map, I just can't remember what bus number it is off hand. Word of advice, give yourself at least 2 hours to get there via public transit.
