Not many trails
I had occasion to visit Biggleswade today, to collect a new shaver to replace one that has gone slow on me (it is seven years old). Having found the staff of Argos freezing next to their open door and commiserated, I wandered down to the nearest bridge over the A1 for some light trails.
Gratifyingly the traffic was quite light for the rush hour, and heavier going north than south. Annoyingly it meant that I couldn't get much of a concentration of light trails – I hadn't bothered to get my tripod out of the car and was relying on the bridge rail and the lens's image stabilisation to keep it sharp.
