"ON YOUR LEFT" we say

[emily_in_nc]

Yesterday riding a multi-use rail trail, I came up behind a woman walking her darling puppy. She never glanced back, so I said "cyclist behind you" as I approached her, so I could see if she moved one way or the other. I also slowed down considerably. She moved right, so I slowly passed her and said "Thanks -darling puppy."

As cyclists, we are the ones who have to be ready to give way, since on most multi-use trails, we are required to yield to everyone else (peds, equestrians, etc). So even if the peds are weaving, listening to headphones, or taking the entire trail, we have to be the ones who stop or swerve or whatever.
But no one says we have to like it!
