HARRISBURG, Pa. --  This weekend help the National Letter Carrier's Stamp Out Hunger.  Letter carriers will be collecting non-perishable food items as they deliver your mail.  To help just place non-perishable food items in a bag and place it beside your mailbox.  All donations will help the people of central Pennsylvania.  The Central Pennsylvania Food Bank says non-perishable donations are welcomed but there is a need for higher end items suck as peanut butter and canned soups.
