Carter spent about 50% off his laps RUNNING full speed around the track. We are going to have to sign up that boy for track when he gets to high school. He's FAST! The other 50% he spent doing this - dancing to the music while walking. I can't believe he had so much energy all day. You can't hear the music well in the video, but it had a good dance beat to it, and he knows how to shake his booty! I wish I would have caught him strutting around to "I'm Sexy and I know it". It was hilarious!
