On my way to work this morning as I approached the side street where The Office is, I suddenly heard a sound coming from below, just behind me. Bright and clear in the brisk morning air, it was the unmistakable ping and rattle of metal skidding on pavement.
I made the turn, pulled over, and parked. I walked back and discovered that it was just the license plate holder that had fallen off.

The rivets holding it on had both broken, and gravity did the rest.
My scoot is registered as a moped (with a sticker), so I don't actually have a plate on it. The only real function this thing serves is to hold the two side reflectors, but that's important enough that I need to reattach it.

Maybe a couple screws will work.
