Practice turkey

I'm researching brining a turkey so that we can test it out this weekend before Thanksgiving. I thought brining was just water, salt and sugar (all of which I have in the house at 10pm), but apparently Alton Brown and the Pioneer Woman want to put stuff like candied ginger or allspice berries or fresh rosemary in it. So now I'm having to decide on a brining recipe as well as decide when I want to roast this bird. Have you all brined a turkey? So you put anything special in, on or around your turkeys to make them wonderful? I'm researching at the last minute!
