(Portland, OR) -- The National Association of Letter Carriers will conduct its 31st annual Stamp Out Hunger Food Drive this Saturday. In Oregon, more than 400-thousand people are food insecure with more than 100-thousand being children. It's easy to take part in the food drive just leave non-perishable food in a bag near your mailbox before the letter carrier arrives on Saturday. The food goes to local food banks and the donations will help them with distributions through the summer.
