My brother and I are taking our families camping on Easter. We would like some feed back on Mckinney Falls. 6 kids ranging in age fom 9 - 16 Heard something about rattle snakes at this park(Is that a problem) heard something about the water quality that could be a problem. Heard it is awesome and beautiful. Have read the park and wildlife description that is not as acuarte as others opinions. Any feed back would be greatly appreciated. thanks
