Hot dogs are a barbecue staple. But the way you make them — and the toppings you put on them — depends on where you live. In honor of Memorial Day, one of the biggest barbecue days of the year, we decided to take a look at how different cities across the country make their hot dogs. Joining us is Tom Raccioppi, owner of Jimmy Buff’s Italian Hot Dogs in New Jersey. Also with us is Mark Flynt, the owner of JS Pulliam Barbeque in Winston-Salem, North Carolina. Stuart Rubin, manager of Mustard's Last Stand, the oldest hot dog stand in Denver. He's from Chicago and serves real Chicago dogs at is stand.
