I grew up in Anderson County. My parents bought a Sears canvas tent big enough for the whole family and a used power boat. It would pull up all five of us young'uns on skis at the same time (but just barely!). We spent our summers on Hartwell.
BTW, there is a Rainman, but he's not me. I'm Rain Man. Just so you know, not trying to be picky. RM matches my real initials.
