Riding on mixed-use path yesterday and noticed 3 children (maybe 9, 7, 6 years old) running back and forth across it, oblivious to traffic potential. Oldest, a girl, had just run across and with a mighty leap jumped over one of the decorative / protective wood timber stubs that line the route on one side (about 2-2 1/2 ft tall). I slowed and dinged my bell a couple of times. Her younger brothers looked up and stayed clear. As I passed, she called out "I like your moustache"
