Protecting The Floors

When we were at Matt's house for Thanksgiving, we set tables up in the living room -- he has a small kitchen, and no dining room. So, the living room was our only option. He has hard wood floors -- I was worried about scratching them with our chairs. I told him he should have put down a couple of area rugs -- but since we are only over there once, maybe twice a year for something like this, I can see why he just gave me this funny look and told me that it probably wouldn't happen. Maybe this year we can have Thanksgiving at our house, and then we won't have to worry about the floors. We have carpeting all through the house.
