Didn't expect that!
A couple of times I've had motorists say something (sometimes even "thank you") about my lights or bright jerseys.
But the other evening just after sundown, as I was heading in the back gate, a kid on a SKATEBOARD came over to tell me he could see my helmet light from "way down at the other end of the street!" That's about 3/4 mile, and he thought my blinking Blackburn Flea was a streetlight going out until he got closer.
I didn't think kids on skateboards noticed!
