DULUTH-The largest annual food drive in the country is hit mailboxes on Saturday.The National Association of Letter Carriers participated in “Stamp Out Hunger”. That's the name of the collection that mailmen and women are a part of on their daily routes.Volunteers also pitched in at Duluth's distribution center and on the road. "Volunteers are really helping out with that. They're picking up the food, sometimes unloading carriers' vehicles,” Scott Dulas, Duluth organizer, said.“Sometimes they're just driving along. We've actually had one time last year and one time this year where the police pulled over the vehicle and ask 'hey, are you stealing food?' and then they see the sign that say they're a volunteer,” Dulas said with a smile. The drive typically brings in about 90,000 pounds of items for Duluth food shelves and 150,000 pounds for the Northland.
