We recently had asbestos taken out of our crawl space where the air ducts are housed. The guys covered up the crawl space with a used piece of wood with what we thought was random paint spray on it. We are going to paint the board white so we didn't care what was on it.... until we looked back at our house from across the street. The spray kinda looked like a swastika. Our thoughts were confirmed when the neighbors commented on it.
I took care of that "Nazi" issue this weekend. The whole thing will be repainted in two weeks.
