I purchased this 5.5lb boneless Prime Rib at Walmart and rubbed it with Lea and Perrin's, salt and pepper. Then wrapped it up and stuck it in the fridge overnight. I don't have enough seasoned logs for my log burner so I'm trying out my brand new WSM! I'm going to try to hold the temp at 225 - 235 and pull the meat at 135. Wish me luck!
