“That’s part of giving back,” said volunteer Greg Broyles. “That’s part of being part of the community. Making sure that people don’t go hungry, especially on Christmas.”

“I think that’s why people come out and help because it just makes them feel good to help someone else And reach out to their fellow man,” Salvation Army Major Mark Nelson told KPIX 5.
