I suppose I would answer it this way: Smoking, deboning, freezing, and reheating would be tastier than waiting until thanksgiving and only cooking it in the oven. However, I personally think poultry is best right out of the cooker, so I think you'd find it better cooked the day of. However, if you're like me and don't want to botch the primary meat source on Thanksgiving, freeze away......and maybe smoke some pulled pork the night before to go along with it!
I think I'm going to try mini-keg-butt turkey this year and see what happens.
