Fair Park is no stranger to animals and, yes, there are heavy weight divisions in two market competitions at the annual Rockdale Fair, but this was somethng special Thursday. Elephant trainer John Walker III waters his gargantuan companions as the Carson & Barnes Circus set up for two shows which played to thrilled audiences. A portion of sales from the two performances raised $550 for Rockdale Rotary Club, circus sponsor. Walker is a sixth-generation elephant handler. Circus coverage page 1B.
