Good morning, I'm David Greene. I know so many of you on the road right now are unsung talents just waiting to be discovered. But please, wait until you're done driving to pursue your art. A Washington state trooper pulled over a semitruck for speeding and found the driver had rigged up a recording studio on wheels. He had a computer, drop-down microphone in the cabin, so he could produce music and drive. Authorities say he was arrested for a DUI. Please, everybody, rock out safely.
