Fast - adj. Done in comparatively little time; taking a comparatively short time: a fast race; fast work.

We spent some time at Kasey Kahne's (NASCAR driver) workshop the other week. He was doing a special event for Make a Wish Foundation and I was there to photograph it. While we waited for them to arrive X got to try out some fast moving vehicles, which made his mom nervous and Xander and his dad excited.

Little man and his papa checking out the Number 9, a very fast car.
Jacob thought it would be cool to see him in the car. X loved that idea, he was giggling like crazy.
Little grin! He didn't want to be taken out.
My boys.
He grew up too fast! How did a little 5 lb baby learn to walk so fast?
