New Documentary Follows Five NYC Families In Tree Selling Business

Eric Kang and his son, Cashmere, are from Canada and now the duo have set up shop on a Brooklyn street to sell Christmas trees. "It does come with its challenges. We're out here in the cold and the rain … the wind," Eric says. They are living where they work, a curbside trailer. Eric was interviewed in a new documentary called "Merchants of Joy." The Amazon Prime Video film takes a look at five families who dominate the tree selling business in New York.
