I've been commuting fairly consistently since October of last year. I've posted here inconsistently.

I'm illuminated like a randonnauer--cycling specific safety vest, ankle reflectors, bright tail light, headlight on the handlebars, and another light on my helmet.

This morning was my first ride in heavy fog. I had no problems with cars coming too close other than a school bus whose driver felt the urge to cross back into my lane fairly close on a 4 lane road. I honked my air horn at her and flashed my helmet light into her mirrors and windows after she passed to make her be better aware of her surroundings.
