The "2014 Chicago Auto Show" opened to everyone this weekend. Hundreds of cars and trucks are packed into the massive McCormick Place Conference Center. Getting a lot of attention is the new Ford F-150 truck. For years this vehicle has been Ford's most popular truck and at the show the 2015 version is now on display. Its body is made entirely out of aluminum. That makes it about 700 pounds lighter--in turn providing for better fuel economy. The first Chicago Auto Show was held in 1901. This is the 106th edition and will run through Monday, February 17.
