Miranda Lambert is taking her On Fire tour all across America with a little extra baggage trailing behind – a 70s Airstream. While writing “Airstream Song” for her album Revolution, Miranda was so intrigued by the trailers that she bought three of them. She tellsValley24.com, she even had one made into a bar so she can “hang out with friends when they come visit.” Miranda and her Airstream will be on the road all weekend as she makes stops in South Carolina, North Carolina and Kentucky.
