Avoiding Turkey Dryness

Turkey dryness, a much discussed holiday calamity.  I can remember my stepmother berating my father over a dry turkey twenty years ago.  I nearly laughed, knowing that the old man had never cooked anything more complex than a peanut butter and bacon sandwich in his life. Stepmother was a dear, but she was a slow learner.
   Anyhow, we had a nice moist turkey this Thanksgiving.  I think the secret lies in a roasting pan with a lid.  The turkey is good and brown after an hour in the oven,  but needs to go another hour or so to be done.  Put the lid on the bird once it is brown enough and it holds in the moisture.  And baste it often.  Modern turkeys are pretty lean, so you may need to use some oil (cooking, olive, anything except 3-in-1) to baste with.
