Questor, here is the way we do it in NC. Pork shoulders cooked slow and low over wood coals, I use Hickory, Apple, and Oak. No rubs, let the smoke flavor the meat, but sometimes I like to put in drip pans filled with apple cider. I make a mop sauce with apple cider vinegar, catsup, apple juice, red pepper flakes, black pepper, cayenne pepper, and lemon. I also make my BBQ slaw with this sauce. Most folks around here like their BBQ chopped, but I prefer mine pulled. We use a 250 gallon oil drum that has been converted to a cooker. For the last couple of years I have had a been using a store bought smoker with a side fire box if I am only cooking 2 or 3 shoulders. I have been very happy with it.
