Rob Portman joined officials from Airstream, Shelby County, and the National Park Service to get a closer look at the new Airstream manufacturing plant. Portman has been an advocate for the parks and believes parks and Airstream go hand in hand. Every Airstream trailer is built in Jackson Center, Ohio, and before the senator leaves office he wants to get one more bill passed to help with the continued success of Airstream and other Ohio businesses in the future.
