A small amount of slippery snow + a large number of cars and lorries + a steep hill = chaos.

The freeway just outside the village plunges down into the valley then climbs back up the other side. If a lorry jackknifes up front with thousands of cars behind then it's finished. 60 people had to sleep in the village school overnight after abandoning their cars...

I didn't do any special noise reduction, just used the DPP software that came with the camera. I hope I'll get the opportunity to try the camera out in daylight at Christmas.
