Followed by boats, swimmers head through Lake Michigan's chilly waters from Chicago August 20, 1963. They're among 20 swimmers trying to reach St.Joseph, Mich., across lake. Leading as picture was made is Greta Anderson, in white cap, Los Alamitos, Calif., last year's winner--along lake shore, not across. Man in goggles is Syder Guiscardo, Mar del Plata, Argetina.
