Saturday will be a busy day for mail carriers all across Berks County.
In just a few hours they will be arriving at front doors across the region not just to deliver mail, but to fight hunger.
It's part of the program Stamp Out Hunger, the nation's largest single-day food drive.
Food in Berks county will be processed by the Greater Berks Food Bank.
Here's how you can help.
"All you need to do is fill that brown paper bag with non-perishable foods. That's anything that's canned, boxed, bagged or bottled, and leave it by your mailbox tomorrow morning and your letter carrier will pick it up," said Doug Long of the Greater Berks Food Bank.
Officials said help is critical, especially with the summer months approaching.
"The reason for that is the children are out of school, and students who are in need who might be receiving a free lunch or possibly a free breakfast during the school year are now home for the summer," said Long.
And given the city of Reading's recent designation by the U.S. Census as the city with the highest percentage of people living in poverty in the nation, organizers are hoping residents will be generous.
"There are signs that the is economy coming around a bit, we're still seeing an increase in the number of local people receiving need," said Long.
