How much is 30 or more pounds of food worth?

Well, for those people wishing to donate such an amount in non-perishable foods at Yankee Stadium on Wednesday, it's worth two free grandstand or bleachers tickets to one of 23 designated games at the Stadium for the 2015 season. Or, they're worth half-price tickets in select general seating areas. Your choice.

The ticket voucher giveaway is part of the Yankees' annual holiday food drive, now in its 21st year.

People who choose to contribute to the team's charitable food drive can drop off their donations at Gate 2 at Yankee Stadium between 10 a.m. and 3 p.m. on Wednesday. Rice and bottled water will not be accepted.

All food collected will be distributed to families in need throughout the Bronx. The Yankees also will donate around 2,500 food vouchers to the recipients of the collected food items.
