If it's a local bird, it won't have the factory saline injections, nor will it be as tender or artificially juicy as a butterball type turkey. Brining will do those things for you, while adding flavor. It's a must do. It's the difference between putting salt on after you cook something and taste it right away or salting it before you cook it, so it works into the dish and tastes seasoned.
There are some great brine recipes out there.
Here is a great article against it.
Let me start this off by saying I don't brine my meat. Ever. Not for Thanksgiving, not for my Sunday supper, and certainly not for a quick weeknight meal. This post is about the reasons why.
It seems to me that as little as 15 years ago, dry turkey was a given. The yearly Thanksgiving ritual at my family's table did not, include any ill-mannered offspring crying out "DAAAAaaaad, Mom ruined the turkey again,"—turkey wasn't something that could be ruined. It was dry, tough, and stringy, and that was a fact of life.
Then, about a decade ago, brining entered the scene.* Thanks to an overnight soak in a salt water solution, gone were the days of dry breast meat and extra servings of gravy. I, for one, welcomed our new moist-breasted overlords. Even my mother could throw a turkey in the oven and pull out something remotely edible a few hours later. It was positively magical!
