Bell? Or Voice?

[Popoki_Nui]

Wennie (but loud!) little bells on three of my bikes. On my Gitane and Falcon, I carry the same kind of bell on a lanyard. It makes the bikes look less cluttered , and I can throw it and bean people not paying attention on the back of the head. Just kidding. Not.
Bells really do get *most* peoples' attention, in my experience calling out/yelling is less effective. I just don't have that powerful a voice, and I'm usually puffing too hard anyway. Besides, the bell makes a really neat sound as it bounces off the backs of their heads. Just kidding. Not.
