I am getting a bit more sensitive to the respiratory hazards of cycling. Today, on my commute to work, I have one section of road that is fairly busy right after my bike path. I was about no get onto it, when a dump truck came by. I waited to enter the highway, and then noticed the plumb of diesel exhaust he had streamed along my route on the road, just as I was climbing a hill. Through heavy breaths, I cursed a bit that the dump truck had decided to come by just before I climbed that hill. Tomorrow, I will probably wear the respirator again.
