I just not had much luck doing unwrapped ribs. Always tough. Many years ago I did ribs on an ECB and they turned out great so I know it can be done. Got smoker going 250 which will probably run closer to 275. Using smoke tube with hickory chips. Following Hey Girl of basting with apple cider vinegar with butter after 90 minutes than every 45. Thinking around 5 -6 hours. Wish me luck. This will be my last try if not turn out.
