Where's Waldo?

We have been meaning to go into Daddy's office and decorate it with a few things.  In this picture, Willow is VERY concerned about the candy bowl.

The plants were intended for the desk but they thought it would look best in front of the window.  However, by the time we left you would have never known a circus came through there.  Maybe I will grab a picture of his office with pictures and the whole nine yards when it is finished. 

I know....random, picture....well, I found about 20 of these pictures on my camera.....I challenge you to see what all of the following pictures have in common besides a road and cars....

.YES, Scarlett took these and told me what she was taking pictures of after I asked who had my camera...I just about fell off my chair laughing.

Do

You

Know

What

Scarlett was taking picture of......ha....

Red Cars.  
I had to go back through the pictures and she was right, she had taken about 20 pictures of the red cars passing by Daddy's office....
