Thousands of volunteers who scoured neighborhoods on a rainy Saturday morning hope to change that statistic — at least for a few months.For the 28th year, volunteers fanned out across the county to collect bags of food and cash donations for the community’s largest one-day food drive, Walk & Knock. Volunteers walked house to house to collect the goods. After filling their cars with donations, they delivered the food to one of numerous sorting centers. There, volunteers unloaded vehicles while more volunteers emptied bags and boxed up the items. The boxes were then loaded into trucks and later delivered to the Clark County Food Bank.
