Not only do I love riding my bike, as many of you know there are plenty of websites out there dedicated to us commuters. One of my favorites is Commute by Bike which is part of the Crooked Cog Network. As many sites do now, you can have them email you updates and articles from the site and today's not only alarmed me but reaffirmed the little voice in the back of my head when riding at night. They attached a graph [because I know how we all love pie charts and bar graphs], that although older data I believe holds very true. It shows when bikes are most likely to be hit.
So be safe, wear a helmet, get some lights, and ride like you're not going to be seen.
