I'm not all that savvy about the company's history or structure, but I think their headquarters was in Norwalk, Conn. when I was growing up. Our neighbor worked there. He was some kind of a manager and he arranged for my Cub Scout troop to get a tour of the bakery. (I almost typed plant).
I vaguely remember the tour but I do remember that each scout got a little six-slice loaf of Pepperidge Farm white bread. Every ate their whole loaf on the way home. It was about a half hour drive. I wasn't checking my watch at the time, I just know that this is how long it takes to get from my home town to Norwalk.
