Wayne homes, both old and new, will be open to visitors next month for the biennial Homes of Wayne Tour that benefits Cary Memorial Library and Wayne Community Church. Among the old is the Harwood Camp, built in 1930 and offering vistas of Androscoggin Lake. The family still gets its drinking water by using a hand pump on the back porch. “We can’t verify this, but my dad, Henry, always said they had to drill through 100 feet of rock to reach water for the handpump well,” wrote David Harwood in a description of the camp that has been in the family for generations.
