Do most of you ride to work in the dark? I have quit riding to work because traffic is so heavy and I have to travel main roads. I really liked to ride in but it just seems so dangerous with the traffic. I can work any time I want to though. I am thinking about going in at 5am so leave home about 4am. then I can also head home before rush hour. Is it safe with a lot of blinkers on a safety vest? I am not really risk adverse, just want it (the risk) to be reasonable.
