This week, Matt Frei completes his tenure as Americana's presenter with a look at why so many Americans fetishize their own history - and why so many others can't even name the Vice President. We'll hear the voices of eminent historians, and ordinary Americans.

Matt also asks author Andrew F Smith about America's unique contribution to culinary history - junk food.

And, as a final lap, Matt tours some of his favorite Washington haunts. Along the way, he checks in with Daily Beast blogger Andrew Sullivan and with some regulars at Ben's Chili Bowl.
