Must be a real well kept secret.
My favorite barbeque is Stanton's fly-in barbeque and fish camp. I know where it is by the air, but for motorists it's somewhere about 40 miles north of Florence about 2/3 the way when you're fling from Charlotte/Rock Hill to Myrtle Beach/Grand Strand.
Next comes the sweet tea thread and the sweet potato biscuit thread. Perhaps then accompanied by a thread on true country ham and red eye gravy.
It's from an area around Columbia, SOUTH Carolina. Maurice's is the most well known, Maurice Bessemer is a Southern Heritage guy and his BBQ joints sell a lot of Confederate and Old South stuff as well. I like the mustard based sauce, but prefer North Carolina.
I like Memphis pork ribs the best, and Lexington-style pork shoulder (coarse chopped, with lots of "brown" (outside charred pieces). I just brought a cooked whole shoulder back from Lexington this week, almost all gone now.
Don't forget the cobbler thread. Nothing beats riding your motorcycle through the Applachian mountains stopping only to sample the cobbler at every roadside restaurant.
