CHARLOTTESVILLE, Va. (CBS19 NEWS) -- Saturday marked the 30th year for "Stamp Out Hunger,” a national event that provides food for those who need it most.

The U.S. Post Office customers are asked to fill a bag with unexpired, healthy, nonperishable food items and place it by their mailbox for mail carriers to pick up.

The Blue Ridge Area Food Bank helps make it happen here in Charlottesville.

This national food drive is the largest one-day food drive in America. With 1.82 billion pounds of food collected since it first started in 1993. It takes place once a year, on the second Saturday in May.

Last year, BRAFB collected 114,000 pounds of food, which provided 95,000 meals for those in need across the community. It's hoping to give even more this year.

If you missed the drive, you can always visit to donate. Every dollar helps provide four meals to area neighbors.
