I don't know about everyone else but I usually cook my turkey or roast a bit higher to start. Usually a half hour to a hour, depending on the size. I find it helps keep the juices in the meat.
Yes the neck is the best part. Luckily my grandfather and I are the only ones that like it. One thing I hate is the gizards lol. I thought I was being sneaky yesterday eating some of the stuffing while carving the bird and I got the heart and I really dont like them haha.
