 While Riverside Amusement Park tried to survive by reducing expenditures (it stayed in business until 1970), White City and Wonderland tried different tacks in trying to boost their attendance to overcome the increased costs of insurance and construction.White City started to emphasize its live performances and its natural settings (offering more activities near the bank of the White River), while landlocked Wonderland continued the upgrading of its mechanical rides.In 1907, White City added "Paris by Night", "Kemp's Model City", a "mysterious flying lady", and a billiard hall.
