This past weekend Mrs. Grouch was needling me about the number of spare wheels that I have hanging in my workshop. I had to gently remind her that it is, after all, MY workshop.
This morning my daughter called. My grand daughter has run afoul of the law, lost her driving privileges, and is depending on her bicycle for transportation. On her way to one of her jobs she had a flat tire. My daughter brought the bike over for me to fix, which I don't mind. Fortunately, I had a correct size wheelset already mounted up with 26 X 1.5" slicks, perfect for a commuter. A shot of air and she was good-to-go. Now I can patch the flat at my leisure.
Take that, Mrs. Grouch, those spare wheelsets come in handy.
