Seconded. I'm making my brine right now - cider, Guinness, honey, allspice, salt, peppercorns and garlic. I'll add ice to it in the morning then brine my bird for 36 hours starting tomorrow night.
I'd also suggest adding some liquid to the roasting pan - red wine or water if you're making gravy from the pan drippings, otherwise a bit of the brine will do.
High heat for 30 minutes or so to crisp the skin and render the fat, then low and slow.
Echoing the others, plan your burner usage well in advance. Do your shopping early too, you will inevitably forget a few things.
Lastly, booze. Plenty of it. Have a great time and Happy Thanksgiving!
