It is amazing that we haven't read about more bicycle accidents during the summer and it should be a credit to the drivers who do drive safely out there. Bicyclists have no idea how invisible they are to the drivers out there, until its too late and the headlights reflect on their blackened silhouettes out there. They wear dark clothing, no helmets and nothing reflective to alert a motorist to what lays just a head of them. In the above picture, there are three people on bikes off to the left side. I was stopped and took this picture quickly and just wanted to make the point that all can not be seen and its unsafe.
So bikers be aware and wear that helmet and reflective clothing, it can save your life.
