the community expanded further westward, annexing 682 acres of land surrounding Lake Forest Academy and Conway Farms Golf Club, despite negative reactions from residents. The city government justified the expansion as necessary to prevent unwanted commercial development encroaching the edges of the community. One of Lake Forest's most notable features is its virgin prairies and other nature preserves. In 1967, a group of 12 long-time residents of Lake Forest formed a land conservation organization, Lake Forest Open Lands Association.
