Man Leads Highway Sing-a-Long [VIDEO]

He's like a Summertime Christmas caroler, spreading good cheer across the highway.

This is TJ Smith.  TJ's a fan of music, and like me will often times belt out songs at the top of his lungs when he's driving.  He found a way to make his passion for sing-a-longs contagious...  On California's Highway 101!
