(COLORADO) — The National Association of Letter Carriers (NALC) is getting ready for its 32nd annual “Stamp Out Hunger” food drive on May 11. It’s the nation’s largest single-day food drive, involving 10,000 communities nationwide.

How to participate:

Leave non-perishable food items in a bag near your mailbox on Saturday, May 11, before the letter carrier arrives. A few days before the drive, your letter carrier will leave a few special bags that can be used for donations. While all donations are welcome, foods that are high in protein, like canned fish, beans, and peanut butter. Canned fruits and veggies, whole grain cereals, mac & cheese, and 100% fruit juice are also among the most needed items.
