I recently got a WSB and I did a 13lb turkey yesterday. The subzero temperatures that were blanketing New England finally lifted that morning and it was about 35 degrees. It felt like a heat wave! I got the smoker up to about 315-320 for most of the cook with all the vents open the whole time, and it was done within about 2hrs 45min. It turned out excellent, though the legs a little dry. This website is great to help us who are just starting out. Thanks!!
