This guy comes past my house early in the morning typically as I am out picking up the newspaper, we live on a hill and he comes by very fast. Last fall his helmet came off and bounced all over the road and somehow he did not notice. (he carries his helmet on the bike rather than his head) I went and retrieved it and stuck it on the fire hydrant on the corner at the bottom if the road. It spent the entire winter there, him passing it every morning. On only one occasion was I outside in time to catch his attention as he passed, but it did not work.

The helmet vanished about a month ago. Maybe it just rotted away.
