In 2005, a former repo man plunked down a hot-dog cart on the 16th Street Mall, an area that had seen plenty of hot-dog carts before. But its owner, Jim Pittenger, definitely wasn't a typical wiener-slinger, and these weren't typical wieners. Biker Jim, as he's now known locally and nationally — thanks to all those Food Network shows on which he's appeared — was doing something outlandishly different: He was vending wild-game sausages (wild boar, rattlesnake, elk and reindeer), and if that wasn't enough to raise eyebrows, he was also festooning his franks with onions marinated in coke and cream cheese that he shot out of a caulking gun. Pittenger is that guy who teaches old dogs new tricks, and now that you can enjoy his gourmet tube steaks in a brick-and-mortar location, you'll often find us scratching at the door.
