Who knew that bowling balls could be a delightfully whimsical edging for a front walk? Having bowled only twice in my life, I had no idea that they came in so many colors. The lanterns hanging from the porch repeat the theme very nicely. How does one acquire dozens of bowling balls? Did someone in the family own a bowling alley? Do bowling balls get too old and too worn to use? So many questions, but no answers. I am too shy to knock on the door and ask. It remains a mystery.
