LOS ANGELES (CBS) — CBS.com Thursday launched a contest where a lucky fan can win a trip to New York City to see the set of “The Good Wife.”

It’s called “The Ultimate ‘Good Wife’ Fan Sweepstakes,” and through a series on online challenges — including answering trivia questions, selecting favorite lines from the show, and commenting on video blogs from series star Alan Cumming — fans will get the chance to win the trip as well as interact with other fans across social media sites.

There is no purchase necessary and the contest is open to all legal residents of the US who are 18 or age of majority in their state of residence.

The contest ends at 11:59:59 PM PT on September 29, 2011.
