How do you think the pedestrian on the path wants to know you are passing them:
1) Yell “on your left”
2) Ring a bell
3) Jingle bells on your bike that rattle that whole time you are riding.
I used to hike every weekend before I started biking. One time this guy coming down the hill and I could hear him for a while. He had like cat jingle bells on his bike. I was thinking of doing that with my road bike.
