When Rich first posted, I was going to surmise that the wheel fell off a bike that was on a car rack. But then my internet connection went down and I forgot. Last weekend I drove off with my favorite winter boots on the top of my car. (I was planning to ride in them, but I don't like operating clutch, brake, gas with them. ) When I reached my destination and realized what I had done, I texted a friend who went and found them. They were neatly together at the curb about a half mile from my house. Picked up and placed there by a shoemaritan, no doubt.
