The cameras are rolling inside the vast, underlit workshop of Orange County Choppers in upstate new york, and it's barely past 10 in the morning. A visitor to this, perhaps the world's best-known custom-motorcycle shop, can't help but get caught up in the lights, cameras and slow-paced action that is american Chopper. Wandering around in search of a restroom, I stumble on-camera, like one of those publicity-starved yokels in the background of a good Morning america broadcast. To their credit, neither paul teutul sr.-the beefy one with the walrus mustache-nor his son, paul Jr.-the thoughtful, oft-abused one-care whether visitors are caught up in the long-running cable-tv series that's made them the public face of motorcycling in the u.s. And 160 other countries. And why should they? The cameras roll five days per week, 11 months per year, blurring the line between bike shop and sound stage.
