The Stamp Out Hunger National Food Drive by the U.S. Postal Service is back and takes place on Saturday.  Danbury Post Office Food Drive Coordinator Charles Volpe says the effort was put on hold for two years due to the pandemic.  Letter Carriers collect non-perishable food donations left by mailboxes and in post offices and deliver them to local community food banks, pantries and shelters.  The food is sorted, and delivered to an area food bank or pantry, where it is available for needy families.  Volpe says it's more important than ever because of the lingering food insecurity from the pandemic.  Most food drives are held around Thanksgiving and the December holidays so supplies are depleted.  Schools will also be out for the year soon and students won't have access to free or reduce priced meals.
