See it all in Charleston. Well worth a visit.
Be careful driving through Columbia on the way to Rock Hill, that "hole to hades" will be opened up at that time of year...hottest place on the face of the earth, it seems. Once you get to Rock Hill, not much to do there, unless you make the drive into Charlotte, which I don't recommend. Theres a Cabela's at the state line, Carowinds boulevard exit, and Carowinds theme park, if you like that sort of thing. Nichols Gunshop is / was close to Rock Hill, I think they're still open.
