new jungle gym?

I noticed it was too quiet so I went out to look for the usual noise culprit Brennen.  Here's where I found him.
I don't know what the draw is but I often find my kids playing on or in my car.  I keep stressing the danger of playing on and in cars but they just don't seem to grasp it.  To them its like another jungle gym.  In the meantime my poor car is suffering the consequences of these climbing natives.  Everyday I see a new scratch :(   my poor car.
