Stripegrill- Congratulations on the new addition. Thats just great.
As far as this topic goes there's another thread in the archives here on just this topic. Its titled "Thanksgiving". It's got some great info fom Dkirn, Airfoils, myself and a guest. Check it out. I remembered typing a rather long post on smoking a big bird (not the sesame street type: before Dkirn critizes my humor
Beyond that I'd say (and this should be no surprise coming from me) GO BIG! I don't care what buterball says, thats not enough meat. In my house 6 of us put a serious hurt on a 20+ lb bird every Thanksgiving and Christmas. Thats the only thing to do if you want leftovers. Which to me is almost better than the firsts. Plus if you've got a group with and overconcentration of dark meat lovers or white meat lovers you'll be thankful for the extra size.
Good Luck and Enjoy!
