Hot dogs, whether tucked in a bun at the ballpark or served on a stick at the state fair, are a great American summertime tradition. Fierce regional loyalties still shape the hot dog business: Many of the dogs produced in this country are made by local, often family-owned businesses, and flavors and styles vary widely from place to place. From North Carolina's peppery red skinless franks to Oregon's salami-like beef-and-pork dogs, from garlicky weiners made in Pennsylvania from a 1939 recipe to Coney Island's famously snappy franks, we love them all. For Independence Day, show off your regional patriotism and order a case of hot dogs from your home state to serve at this year's barbecue.
