If the thought of driving a bit doesn't bother you, the Clemson Gaming Guild has a pretty active wargaming crowd, with 40k and Warmachine being the top two games. They meet at the old student union every saturday at 3:00. Just plan ahead and check to see if there's a home football game before coming, and if so, try to arrive earlier; parking is a nightmare on game days.
PM if you're interested, and I'll provide the email addresses of the folks in charge, who will be able to give you more information.
