From my side view mirror...

Matthew's feet. Yes, I'm one of those parents. 

ps, there was virtually no fighting in our car while traveling to and from Utah. Maybe because I let them lay down and stick their feet out the window.

Yes, I'm one of those parents.

(They did not lay in the back window, sit on homemade boosters made out of pots and old pillow stuffing or pee on the side of the road...but I may or may not have when I was their age.)

 I don't know how well you can see it, you may have to click on the photo, 

but the mountain in the mirror is Mt. Hood.
