World's largest steamboat gets a $6 million refurbishment


With its iconic red paddlewheel propelling it along, the world's largest steamboat, the American Queen, has returned to the Mississippi River in her first voyage since 2008.

The slow-moving time machine, which harkens back to the 19th century, was christened Friday in Memphis as it left for a seven-day cruise.
