On May 16 at 7:00 pm in locations all over the United States and in several other countries, a Ride of Silence will be held in honor of those who have been injured or killed while cycling on public roadways.
I am planning to do this ride, probably with the kids. I think it's a good idea to bring attention to this issue during Bike Safety Month (May). As someone who puts a couple thousand miles a year on various bicycles the issue of cyclist safety is never far from my mind, especially after the death of a local triathlete in May of last year in a collision with a truck on a commonly-ridden cycling route.
