"So when you go to make bread the next day the stone is not in the oven, and you think someone broke into your house during the night and the only thing they stole was your pizza stone. (This may sound far-fetched, but if you have children the misappropriation of your stuff, such as extension cords and tools and tomato sauce, is an all too common experience.) Then you remember it is on the grill." . . . . .
