Jane and Michael Stern on the Origins of Roadfood

Serious eaters who have been around awhile, like me, know that the idea of driving across America in search of the best regional food originated with Roadfood authors Jane and Michael Stern, not Guy Fieri: They published their first edition of the guide in 1977–one of 30 books they've written to date, including 10 editions of Roadfood–decades before Guy started tooling around in his convertible on TV. Along with Calvin Trillin, the Sterns have been my greatest inspirations, so I jumped at the chance to interview them on Special Sauce.
