Andresen/St. Johns — The Walk and Knock charity recently gave $20,000 it raised from local donors to the Clark County Food Bank. The food bank will use the January donation to buy food for the hungry. In addition to accepting money donations, Walk and Knock volunteers spend the first Saturday of each December going door-to-door collecting food. During its 25 years, the nonprofit group reports gathering more than 6 million pounds of food worth nearly $8 million. Learn more at www.walkandknock.org.
