Wednesday is shaping up to be a big day at the New York State Fair.

Justin Bieber and Lady Antebellum will both be performing, setting the Fair up for a possible record-setting day.

Fair Director Dan O'Hara says he's expecting over 100,000 people to come through the turnstiles Wednesday, and the all-time Wednesday attendance record of 112,000 could be broken.

O'Hara says there will be extra security on hand for the huge crowd they're expecting.

Lady Antebellum will put on a free concert at Chevy Court starting at 8 P.M. Fair officials say they are expecting 20,000 people, which would break a Chevy Court record.

Vendors are also excited for the big night. Many were let down when Justin Bieber's concert was rescheduled from Sunday to Wednesday, but now hope to recoup some of those lost profits.

Bieber's concert start at 7 P.M at the Fair Grandstand. Fair Officials recommend arriving a couple of hours before the concert.
