Like other cities, Davis is home to people who have no home. And so each year the Interfaith Rotating Winter Shelter, a project of Davis congregations (mostly churches), offers overnight shelter and food to the homeless for a week at each of 10 locations. It runs from December to mid-March. Linda Scott, co-chair of the shelter and a longtime volunteer, talks about how it works, what it offers, recent changes, the main cause of homelessness among the people they serve, and the contributions of their 1,500 volunteers. The shelter helped about 140 people last year.
