A full day of family fun is planned as the park celebrates a milestone anniversary on McCormick Day, the birthday of Cantigny benefactor Robert R. McCormick (1880-1955). Kids enjoy vintage games and crafts plus a concert by Miss Jamie & The Farmhands at 2 p.m. The Barefoot Hawaiian performs at 5:30 p.m. Plus, birthday cake cutting and a vintage baseball game. “A League of Their Own,” parts of which were filmed at Cantigny, will play continuously in the Visitors Center theater. The special day will be capped by a Ravinia-like concert by Chicago Sinfonietta at 7:30 p.m.—under the oaks outside the First Division Museum.
