 I didn't know if other sides get beaten up. And we had the call a little bit earlier. We do have open phone lines before we go out to our news break. A call about wood siding. Tell me about the different types of siding. You mentioned vinyl siding, which is probably the most common. What other types of siding or different types of roof materials do you find that are really benefited by cleaning in with low-pressure pressure wash professionally, though? Sure. People have hardy plank or aluminum siding, cedar siding.
