re: New York City subway scam artists who buy low-cost all-day subway passes and then swipe passengers through the turnstiles in exchange for cash or tokens.

all day cards can only be used once (in a half hour) at the same subway station...

swipers do work some stations, but they have 3 or 4 or even a dozen cards, and they get chased away...
and smart NYer's will use them once in while, but only pay $1, not the $1.50 that is the real fair.

the NYC subways system is one we NYers love to hate.. it runs 24 hours a day, lots of express lines, and cover 90% of the city. but there are delays, and problems, and its impossible some times to get from point a to point b--
for example, i am planning to move about 8 mile from where i now live. to get from north queens, to central queens, i would almost have to go into manhattan. to get to south queens i would have to go via manhattan.. same is true for west bronx to east bronx... the system is manhattan oriented.
