Place ribs in rib rack on hot grill over drip pan (or place ribs, bone sides down, directly on hot grill over drip pan). Cover, grill and cook 2-1/2 to 3 hours or until ribs are tender. If using charcoal, add 10 briquettes and a handful of soaked wood chips to coals every hour. For gas grill, add some wood chips to the smoke box every hour.
