What does it mean when you hear a loud continous clanking sound from the back of your car as you drive?
I don't know either, which is why I stopped my car aside for a check when that happened last Tuesday evening. As it turned out, I had a flat. A long big bolt had somehow punctured the side of my tire. That sound was the sound of the bolt's head hitting the tar road as the wheel spins. I am glad I had a spare but I still can't figure out how the bolt got there.
And now I got to get a spare's spare since the spare I had is used and I no longer had that spare as spare for another time that I would need a spare. Dollar notes flying away again. Siennn!
