I am blessed/cursed to live next to an extensive "bike path" network. This path is my start to almost anywhere I want to go.

Joggers, strollers, walkers, little old ladies that have been in their own world since 1962 and a lot of other people that have never conceived the idea that there could possibly be a bike on the bike path also use it extensively.

Being blessed with a fairly deep resonate voice when I say "on your left" some people go into a total panic, other turn (of course) to the left. I have tried shouting at the ones with the headsets on, flashing lights and throwing small to medium size rocks.

The only thing that I have found that does not scare the people but the hear and notice with out panic is a "little childs bicycle bell" a ding-a-ling.

They hear it and step to the side with no problems.

This could be some type of Oklahoma anomaly, but I thought I would pass it on to see if it might work for you.
