4x4 ing down the stairs

I should have known that eventually this would happen. Call me naive or whatever, but I had thought he had the hang of our house layout. Apparently I was wrong. Gabe apparently misjudged the amount of room between the front tires of his 4x4 and our stairs.
The truck was unhurt......Gabe not as fortunate. He will have yet another fat lip for the next week or so.
