I want to comment on Jeff's recommendation of not smoking a turkey over 12lbs. For the last several Thanksgivings I have smoked at least a 20lb turkey. The way I figured out to get it done throughly was to put it on a beer can chicken holder without a can in it. It opens up the cavity of the bird and still turns out nice and juicy. I just wanted to pass this along to see if anyone else has tried this.
