"On your left" - What does this mean to you?

[kenyonchris]

Dogs on retractable leashes--I just cringe and wait for impact as I go over my handlebars.

DONT'T even get me started on those retractable leashes!!! I have had so many near crashes on patrol while riding on the path (which I never do on my personal bikes for all these reasons)...and seen many non-doggie people very unhappy when accosted by a dog on a retractable leash.
My dog heals when in public on a leash. Makes life better for him, the people around me, and me.
Those things are nuisances and dangerous.
