The new Roadfood book is out, and newspaper editors all over the country are leafing through it to find the local spots that made the cut.  The Des Moines Register spoke with Michael Stern by phone about Iowa's Roadfood eateries, and Roadfood in general.  Our favorite quote by Michael: "food in a cultural vacuum is of no interest."  And, as so often happens, the Register refers to Jane as Jan.  Sorry, Jane; you just don't seem like a Jan to us.
