Michigan winters produce unending demand for an important product: warm socks. While many people take them for granted as an afterthought in the grand scheme of apparel, for those in need, good socks can be a critical resource during an icy winter. In a press release Thursday, the Three Rivers Woman’s Club (TRWC) announced it is not only continuing but expanding its “Socks for the Sole” campaign, which it founded one year ago. The campaign collects donations of socks for those in need.
