Tomorrow is the final day of the Letter Carriers' (NALC) 21st annual "Stamp Out Hunger" Food Drive. It is the largest annual food collection day in the United States. In 2012, the drive collected more than 70 million pounds of food, and it has collected nearly 1.2 billion pounds of food since it began in 1993.
 

The drive is held every year on the second Saturday in May, with letter carriers across the country collecting nonperishable food donations from customers. Donations are given directly to local food pantries and, in 2012, about 30 million people were served. While most food pantries receive the bulk of their donations around Christmas and Thanksgiving, the NALC drive is done in the spring, when many food pantries are struggling.

Leave a bag of nonperishable food items next to your mailbox for your letter carrier to pick up. 

NALC President Fredric Rolando said:

On the second Saturday of May each year, thousands of letter carriers step forward and join our co-workers, family members, friends and community partners to pick up those all-important and often heavy sacks of donated nonperishable food items left by mailboxes. To get us there takes the dedication of hundreds of branch food drive coordinators, who have spent the last few months ordering and mailing countless customer-reminder postcards, putting up food drive fliers and posters and so much more—often after spending the day delivering the mail.
