Pre-heat the oven to 300 degrees. Apply dry rub to both side of the ribs. Bake the ribs in the pre-heated oven for 3 hours. Finish cooking the ribs on the grill over medium heat for a smokey finish. Warm the barbecue sauce slightly, then slather it over the cooked ribs for a fall off the bone delicacy. Serve with baked beans and an ear of fresh corn. A slice of watermelon completes a delicious, savory meal.
