Wonder Bread hasn’t been available in Washington state for two years? I never noticed. And it seems that many in Southern California may not either, as Interstate Bakeries Corp. is now closing down Wonder Bread production in that area. The company has been operating in Chapter 11 bankruptcy for 3 years now. The bakery closures will not affect its money-making snack lines of Hostess Twinkies, Ding Dongs, Ho Hos.
