I have no connection to this at all but the contest link wasn't prominent on the Sam's Club website so... maybe there won't be a lot of entrants.  I don't qualify for it as I'm not a US resident but most of you are so if you want to enter, it's totally free:

Prize includes round trip airfare, 3 night's hotel, tickets to a party on Thursday (doesn't say which one), first floor Clubhouse tickets (so that means on the apron) for both the Oaks and the Derby, access to the race club at the hotel, a VIP fast access pass for winner and guest (whatever those mean), a gift bag for winner and guest, ground transportation to and from hotel and events and a check for $750 for spending money for the winner.

Good luck and please post if you do win :-)
