re: advocacy in the advocacy thread
Sadly, there isn't much of that and I'm very happy this thread exists in the A & S Forum, even if 2 months go by before people post in it.
I rode today in a university study analyzing particulate exposure in cyclists' lungs while riding. There were pulmonary function tests before a measured ride, then after, then 2 different times after the ride. I'll get an air pump out of the effort, as well as helping someone study cyclists in their environment.
