MISSOULA, Mont. -

Mail carriers worked to Saturday to Stamp Out Hunger.

It's a nationwide food-drive where postal workers drop off the mail on their normal routes, and then pick up non-perishable food people leave by their mailboxes to donate to local food banks.

Missoula Food Bank Communications Director Jessica Allred said this is their biggest food drive of the year. She says she hopes today?s haul will help them get through the summer.

"Summertime is typically our slowest time of year for donations of both cash and food,? said Allred. ?So if we can build an inventory going into those summer months, it makes it a lot easier for us to be able to keep food on the shelves."
