Generations of swimmers in the Northern Virginia Swim League know the Overlee Clubhouse on Lee Highway, Arlington. Thousands of youngsters literally competed in its shadow. Built in the 1880s for the Febrey family, and long the home of the Kincheloe clan, it was a sanatorium until purchased by the Overlee Community Association over 50 years ago. Preservationists lament the loss of the historic structure. Old-timers are left with memories. The house simply wore out. Plans to save it made no economic sense. A modern replacement overlooking a new pool will be completed before the summer season.
