At the very end of this youtube video, you can see the washer and dryer on the back wall of the garage, at the left.
I know there were other times when the protestors were out front, etc. that we could see into the garage, but I haven't been able to find any yet. I know they are in the garage, when I heard in the beginning that CA washed the clothes from the car it made sense because the washer was right there by the car.
The video of the house for sale in fla*mom's post also shows a doorway between the dining room and kitchen. It doesn't look like there is room for the hallway from the bedrooms and the bathroom to open into the dining room or kitchen. There was a video of CA being interviewed at the dining room table and I could see a doorway into the kitchen behind her and farther past the doorway could see the faucet from the kitchen sink. Can't remember who was interviewing her though.
If there is no hallway going through to the kitchen or dr, then Casey would have had to walk through the living room anytime she left the house. So if George was watching tv, she would definitely have had to walk right by him.
