Tracen sure loves any time that is spent with his Dad.
Luke was right when he thought that Tracen would enjoy watching the car being washed. As evidenced in the picture below, it was a hit:
Tracen is into cars (mostly of the Pixar kind) so this kept him happy and amused.
He made sure to watch closely.
And just like his Dad, he has an eye for detail when it comes to cleaning and pointed out when a spot was missed.
(This picture makes me laugh because of the difference between Tracen's arms and legs, it isn't a shadow, his legs are sure getting dark from sticking out in the stroller).
