A tip to Laguardia:

For those of you with a sense of adventure, you can take the N train to 30th Street in Astoria. Take the stairs down from the platform, and there is always a gypsy cab that will take you to Laguardia for $10. Just look lost for a minute or so, eventually someone will beep at you. Remeber, always ask the price before getting in (the key for any gypsy cab)
