People also can bring food Sunday or Monday to any of 50 sites listed at: http://walkandknock.org/one/volunteer_barrels.htm.Justin Lee knows that food will be in short supply this winter for some of his fellow Mountain View High School students. That’s why Lee was happy to join 4,000 other volunteers Saturday in the 27th annual Interservice Walk & Knock food drive.Lee was among those working at a drop-off site at Crestline Elementary School in east Vancouver. It was one of 11 transition points around Clark County where people who’d toured local neighborhoods brought bags of donated food so the cans, jars and boxes could be crated and loaded on a truck.“I also work at Open House Ministries, and I know students from Mountain View and the Evergreen school district who get help there,” Lee said. “I definitely know this will help people. It’s nice working in your own community.”The total take in all those bags and boxes amounted to about 140 tons of groceries.While it was not a record, “It was a good return,” said Walk & Knock President Joe Pauletto.The event always is held on the first Saturday of December, but it’s not too late to give.“There still are barrels out at drop-off sites where people can leave food,” Pauletto said. The organization also will be tallying cash contributions over the next couple of weeks.
