well since the quiz tonight was postponed and it was cooling outside i took the opportunity for a bike ride, my normal short route (8.7 miles) left just before 9pm, and by the time I turned around to head home was using the lights for the first time, I have to say they do a good job, just arrived home, so it was a quick run at just about 1 hour, the only issue with the riverside route, ploughing through what felt like a sandstorm of flying bugs.
