Letter carriers throughout the country will try to "Stamp Out Hunger" as they pick up donations at mailboxes this Saturday. Jean Kempe-Ware with the Oregon Food Bank says they want nonperishable items only, such as canned goods, including protein, rice, pasta, baby food and powdered drinks. She says letter carriers are leaving degradable plastic bags they want postal customers to fill.  Those bags must be left at your mailbox early Saturday; carriers will pick them up and get them to local food banks for distribution.
